As a general rule: work one small step at a time.

So step back from your cake application as it currently stands and write something with a single button that makes a single change to the GUI. Then, when you have something that does what you want, apply it as a "pattern".

Quite likely the problem lies in the fact that your action handler doesn't cause a repaint.
