Which Pyton Book For Newbies?

[W. D. Allen]

I want to write a retirement financial estimating program. Python was 
suggested as the easiest language to use on Linux. I have some experience 
programming in Basic but not in Python.

I have two questions:
 1. What do I need to be able to make user GUIs for the program, and
 2. Which book would be easiest to use to learn Python programming?

Thanks,

WDA
