Not going to do too much bla bla..

Just open up Netbeans Ide

create new project—>java—> java desktop applcation

Switch  to design View Take a Jbutton from the right side of Ide Palette

Right Click Jbutton You will see

Events—>Action—>ActionPerformed

Click it you will be automatically Switched to Source View

You will see code like this

 1: private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) 
 2: { 
 3: System.exit(0);//Closes Jframe with exit code '0' 
 4: }

Now Run and compile it press Jbutton It closes the jframe

Thanks
