Essentially what you have to do is make the outer part of your JFrame rendered surface transparent and then draw your own custom shape in the middle.

This will get you started:

And this is a finished implementation:

//You can change the shape of JFrame import java.awt.geom.*;

setUndecorated(true);
Ellipse2D.Double E=new Ellipse2D.Double(0,0,500,500); //nested class Double## 

 - Heading

 ##
setShape(E);
setVisible(true);
