iPhone design question

I want to display a scrolling menu in my application. The menu has a
number of buttons. Each button will display a different tableview
controller when clicked. I dont want to use a tabbar controller to
manage the different views because I want to use that to manage
different groups of related views, including this this one. My question
is:
What would be the best way to go about this?

Currently, I'm drawing my scrolling view in my app delegate. The button
actions are in my app delegate as well and when one is clicked, the
appropriate view is pushed on to the stack.
TIA
