magento tabbed backend like catalog/product for custom entity

Question

I want to write a module with a custom entity. In the backend it shall look like the backend from products (tabs on the left, forms on the right).

I tried many variants and inspected/copied many things from the core to understand it... well I don't.

Knows anyone a tutorial or the neccessary key points to realize this?

Many thanks

Edit: well, it's not the problem to create own entities, this is well known. I need help to create the backend, so that the result looks like the tabbed form when editting products

For adding multiple tabs in admin first go through the http://codemagento.com/2011/02/grids-and-forms-in-the-admin-panel/ provided by mpaepper.

after that create below class

Super_Awesome_Block_Adminhtml_Example_Edit_Tabs
Super_Awesome_Block_Adminhtml_Example_Edit_Tabs_Form
Super_Awesome_Block_Adminhtml_Example_Edit_Tabs_SecondTab

and modify the Super_Awesome_Block_Adminhtml_Example_Edit_Form to

class Super_Awesome_Block_Adminhtml_Example_Edit_Form extends Mage_Adminhtml_Block_Widget_Form
{
    protected function _prepareForm()
    {
        $form = new Varien_Data_Form(array(
                'id' => 'edit_form',
                'action' => $this->getUrl('*/*/save', array('id' => $this->getRequest()->getParam('id'))),
                'method' => 'post',
                'enctype' => 'multipart/form-data',
        ));

        $form->setUseContainer(true);

        $this->setForm($form);

        return parent::_prepareForm();
    }
}

Add below code

class Super_Awesome_Block_Adminhtml_Example_Edit_Tabs extends Mage_Adminhtml_Block_Widget_Tabs {

    public function __construct() {
        parent::__construct();
        $this->setId('awesome_tabs');
        $this->setDestElementId('edit_form');
        $this->setTitle(Mage::helper('awesome')->__('Your Title Here'));
    }

    protected function _beforeToHtml() {
        $this->addTab('form_section', array(
            'label' => Mage::helper('awesome')->__('Details'),
            'title' => Mage::helper('awesome')->__('Details'),
            'content' => $this->getLayout()->createBlock('awesome/adminhtml_awesome_edit_tab_form')->toHtml(),
        ));


        $this->addTab('secondtab_section', array(
            'label'     => Mage::helper('awesome')->__('SecondTab'),
            'title' => Mage::helper('awesome')->__('SecondTab'),
            'content'   => $this->getLayout()->createBlock('awesome/adminhtml_awesome_edit_tab_secondtab')->toHtml(),
        ));

        return parent::_beforeToHtml();
    }

}

...

class Super_Awesome_Block_Adminhtml_Example_Edit_Tabs_Form extends Mage_Adminhtml_Block_Widget_Form
{
  protected function _prepareForm()
  {
      $form = new Varien_Data_Form();
      $this->setForm($form);
      $fieldset = $form->addFieldset('awesome_form', array('legend'=>Mage::helper('awesome')->__('Header text here')));

      $fieldset = $form->addFieldset('example_form', array(
             'legend' =>Mage::helper('awesome')->__('Example Information')
        ));

        $fieldset->addField('name', 'text', array(
             'label'     => Mage::helper('awesome')->__('Name'),
             'class'     => 'required-entry',
             'required'  => true,
             'name'      => 'name',
             'note'     => Mage::helper('awesome')->__('The name of the example.'),
        ));

        $fieldset->addField('description', 'text', array(
             'label'     => Mage::helper('awesome')->__('Description'),
             'class'     => 'required-entry',
             'required'  => true,
             'name'      => 'description',
        ));

        $fieldset->addField('other', 'text', array(
             'label'     => Mage::helper('awesome')->__('Other'),
             'class'     => 'required-entry',
             'required'  => true,
             'name'      => 'other',
        ));

        if (Mage::getSingleton('adminhtml/session')->getExampleData())
        {
            $data = Mage::getSingleton('adminhtml/session')->getExamplelData();
            Mage::getSingleton('adminhtml/session')->getExampleData(null);
        }
        elseif (Mage::registry('example_data'))
        {
            $data = Mage::registry('example_data')->getData();
        }
        else
        {
            $data = array();
        }

      return parent::_prepareForm();
