Nothing is impossible with open source ;)

What's possible for you depends on your knowledge and the amount of effort 
you are willing to spend. The page you link to has the comment

"""
The 2to3 route is not likely to apply since ctypesgen actually writes Python 
code and the 2to3 utility will probably miss a good portion of that logic.
"""

But as someone else seems to have done the work already

https://github.com/davidjamesca/ctypesgen/issues/51

I'd try his version first.
