multiple choice window question

[Caesium]

Hi!

I'm trying to merge some modifications.
While doing this, I had an idea.
How would it be, if there was a menu popup before the first turn where I could choose, which integrated modification i would like to activate for the game and which not.
My vision is a multiple choice window that returns a value for each modification to the CvEventManager.py; from this point I know how to program this.
But how to program a popup window with multiple choice options that returns these values?
If someone's got a hint, I would be very pleased.
