what you want to do can be achieved by creating your own inherited class of a control. e.g.
public class yourbuttontemplate : System.Windows.Forms.Button
{
yourbuttontemplate() //constructor
{
this.Height=20;
this.Width=40;
this.BackColor=Color.Blue;
}
}
Once you build your project, your button should be available in the toolbox and you can use this button instead of the default Windows.Forms.Button.
