I hate trying to answer questions like this (IANAL etc), but here goes...

If your code imports a GPL module then it is a derived work in the same
way that C code linked against a GPL library is a derived work. If you
want to distribute your code then you must use a GPL compatible license.
py2exe doesn't make any difference to what you can and cannot do.
