fatApp.setSize( 280, 200 );
This is a matter of trial-and-error. There are better ways to do this which use additional features of Swing. Another useful thing to do is to give the entire frame a title. This is done with:
setTitle( String title )
Now the top bar of the frame (the one that contains the "close button") has a title.
