The table below will list all extensions I've created and with which compiler. As you can see, all of them are version independent except for IMDbPY, OpenGLContext, py2exe and pycrypto, which are currently only compiled for a specific version (2.4 or 2.5 - see below). See the distutils docs for more information on version independence.
Check out PyPI to see how many I'm missing: http://pypi.python.org/pypi
You can create these binaries in the following way:
1) Download the module
2) Navigate to the directory that holds the setup.py file of the module from the
command line
3) Run python setup.py bdist_wininst
or python setup.py bdist_msi
4) In some cases, you may need to compile the module's dependencies and link to
them to get the bdist command to work.
Note on testing: If there's a usable test module included with the source, then I will use that to test the installation, otherwise I will wait for community feedback and update as necessary.
It should also be noted that all I did was create the binaries. I did NOT create any of the source code. Please refer to the appropriate website(s) for documentation. I'll be happy to work with developers to get their extensions compiled. Also I make no warranties about any of this code. It was compiled from the sources found at the links listed. Use at your own risk.
