I didn't read all your code but you can have a JButton which has some text on it. by either calling the setText method, or setting the text in the constructor

JButton b = new JButton("Set in constructor");
JButton c = new JButton("");
c.setText("Set via setText");

You can also make the button un clickable with

c.setEnabled(true);

Another good way would be to use a JLabel, which sets the text in the constructor or via setText method.

c.setEnabled(true);

Um, false

Oops, I suppose the name implies what true would do. Thanks for the correction.
