Answer 1

JScrollPane pane = new JScrollPane();
JPanel panel = new JPanel();
panel.add(pane);

Answer 2

Instead of setting null layout for your JPanel, set BorderLayout and everything should work fine like in this example:

import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import javax.swing.JTextArea;
import java.awt.BorderLayout;
import javax.swing.JScrollPane;
import javax.swing.JPanel;

public class App extends JFrame{
    JPanel panel = new JPanel();
    JTextArea textarea = new JTextArea(10,50);


    public App(){
        panel.setLayout(new BorderLayout());
        panel.add(new JScrollPane(textarea),BorderLayout.CENTER);
        add(panel);
    }

    public static void main( String[] args ){

        SwingUtilities.invokeLater(new Runnable(){
            public void run(){
                App a = new App();
                a.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                a.pack();
                //a.setSize(1900,1200);
                a.setVisible(true);
            }
        });    
    }
}

So, just add your form instead of JTextArea.
