Animated menu

I would like to create an animated menu, like the one I made in this game : www.firstrategames.com/demo.aspx?id=1
This example was done in Flash, I created a class for it, so I was able to do things like:

myMenu.addMenuItem(buttonText, command);

and

myMenu.addSeperator();

then I could add an eventlistener to this menu like this:

myMenu.addEventListener("onMenuSelection", this);

So, when you made a selection it would dispatch an onMenuSelection event, and send the command string with the event object.

When you roll over the mouse, the menu items appear one at a time. It looks a lot nicer then just showing all items at once. The menu class then checks the mouse position each "tick", and highlights the selected button. onRollOut, the menu items are hidden again.

Now, how would I do this in TGB/TGE? Is there a way I can script this? Or do I have to do this in C++? I'm just starting out with things like this.
