1. To use Button's getLabel() method you must cast the Object returned by getSource() to a Button
2. You can't compare Strings with ==, use equals(String) instead, if you must.
3. If you want to know which button was pressed, test that directly

if(  (ae.getSource() == ok) ...

just remember to declare ok as

final Button ok = new Button("ok");

in your class, not in the init method.
