there are set of methods implemented in API that created undecorated JButton, e.g.

button.setBorderPainted(false);
button.setBorder(null);
//button.setFocusable(false);
button.setMargin(new Insets(0, 0, 0, 0));
button.setContentAreaFilled(false);
button.setIcon(myIcon1);
button.setRolloverIcon(myIcon2);
button.setPressedIcon(myIcon3);
button.setDisabledIcon(myIcon4);
