Yes. Python Windows devs get it for free from MS.

I believe the intention is to release 3.3 compiled with VS 2010. Brian 
Curtin and Martin Loewis are working on that. I believe people have 
successfully built at least the basics with VS2010.

You could also dual boot to Linux and get 64 bit gcc for free.
