Sockets are nice and simple.  Depending on what you're doing,
stdin/stdout may be even simpler.

For the RS232 part of the problem, don't forget about pyserial:

I've occasionaly used mingw (which _is_ gcc), and it worked well.
Cygwin (also gcc) works well, but it's a bit more involved.

I do all my embedded development on a Linux host.  I find Linux to be
far more suitable for the task -- the entire Unix system basically
evolved as a software development platform.  I've yet to figure out
what MS-Windows is suited for other than lining Bill Gates' pockets.

Before Linux, I used Solaris/SunOS, and before that I used Unix V7.
Everytime I've been involved in a Microsoft-hosted embedded
development project, I just end up walking a way afterwards shaking my
head in puzzlement.
