Creating a sliding gui

Howdy,

I'm developing something targeted at the iPad and was wondering if anyone could point me towards resources useful in creating a menu that slides out when a hotspot is hit, ideally being draggable would be best but I can settle for a simple 'touch - > slide out' ' touch - > slide back in' style solution!
