Your ActionListeners could set a boolean member variable to false or true,
depending on which button was clicked. Add a nice convenience method to
your class (which extends the Dialog class) that basically does just this:

private boolean confirmed= false; // set by the ActionListeners
...
public boolean isConfirmed() {
   this.setVisible(true); // this thread will be suspended by the modal dialog.
   return confirmed;
}

In your calling code you just have to do this:

if ((new YourDialog(...)).isConfirmed())
   // user pressed the confirm/ok/save whatever button

Your constructor initializes the entire YourDialog object but doesn't set it
visible yet; that's the task of the isConfirmed() method.

kind regards,
