I'd rather go for Linux Mint.
NO, it is not complicated.
NO, you do not need to know programming.
It is just a very good operating system, and coning from windows, you will have no problems using it. Only limit is standard mac/windows programs like photoshop, ableton live, final cut.
Drop me a line if you have any questions.
Linux I've been curious about for a while and would definitely like to experiment around with it! I'll definitely ask questions along the way.

Linux comes in different forms and shapes (called distributions); I'd make sure to use Linux Mint, as it is the most user friendly version.
