Advice if its most appropriate to choose "scene" or "ui"

[guran]

I've just started working with Pythonista and am trying to write a script that will start by posting a background image and then a number of buttons that will open new windows with new content if you press any of them... I want it to work on iPad and iPhone.
Can I get advice if it is most appropriate to choose "scene" or "ui" to work with?
Also if someone maybe have a simple script to share, that I can start from, so I understand the structure , would be grateful?

@guran Pythonista doc says "The scene module provides an easy way to create hardware-accelerated 2D graphics and animations, specifically games."
Thus, in your case, I should use ui.
