Maybe you can help me with a more general question: My group writes python code (including c extensions) on linux/mac, then distribute a windows installer using distutils bdist_wininst. The presumption is that you can expect to do that without Windows-specific development expertise. Is that a realistic expectation?
What compiler are you using? If it's not msvc, then no, this is not a realistic expectation. If you do build on Windows with the right MSC version, then you can probably manage by paying someone once to set the build process up, and then only running the build process. There is a good chance that you break the Windows build every now and then, and then it will be very time-consuming to diagnose the problem and fix it, without expertise (roughly the same is probably true if you target any other system without knowing what you are doing).
