I'd also recommend starting with Python, there's a pretty good beginners' tutorial here:

http://en.wikibooks.org/wiki/Non-Programmer's_Tutorial_for_Python_2.6

http://en.wikibooks.org/wiki/Non-Programmer's_Tutorial_for_Python_3.0

There's 2 different versions of the book, depending on which version of Python you want to use. If you're unsure which to choose I'd suggest going with v3.0 as it's the latest version.
