Move you code in onModuleLoad to a seperate method (start() in my example)
In onModuleLoad create a window with a button that lunches your app.

    public void onModuleLoad() {
        final Window w = new Window();
        Button b = new Button("Start!!!", new SelectionListener<ButtonEvent>() {
            @Override
            public void componentSelected(ButtonEvent ce) {
                w.hide();
                start();
            }
        });
        w.add(b);
        w.show();
    }
