+1 to Igor and Alex. Here's some code you can use, if you want to use the ClosingHandler:

    Window.addWindowClosingHandler(new Window.ClosingHandler() {

        @Override
        public void onWindowClosing(final ClosingEvent event) {
            event.setMessage("Don't you think my site is awesome?");
        }
    });

Some info from the Javadoc of ClosingHandler.onWindowClosing():

 /* Fired just before the browser window closes or navigates to a different
  * site. No user-interface may be displayed during shutdown. */
