Best way to design an iPhone app?

I'm looking to design an iPhone app. I have no experience coding or anything but thankfully the design will be very simple.

All I need is an easy way to make a menu, have four options in that menu, then 50 more options for each of those options. Essentially just folders inside folders. Then I need the user to pick values 1-100 and be able to multiply some numbers depending on the values they put.

What's the best way to be able to design an app like this? Please give me names of programs I should try to use.

Xcode
