then use void setSize(int, int) of the JFrame class in your buttons
actionEvent function.

See http://mindprod.com/jgloss/jbutton.html
to write an ActionListener.

Then have it so a setSize, and revalidate on your window.

I think, the window's decoration already includes such a button.
Isn't it the one with the rectangle in it ?
