That's great, but yeah. In case it helps as a data point, I consider
myself a reasonably technical guy, probably more than your average
python package author -- 15 years of free software hacking, designed a
pretty popular X remote display protocol, helped invent DVCS, have
written patches to gcc and the kernel, numpy co-maintainer, etc. etc.

For the last ~12 months I've had an underlined and circled todo item
saying "make wheels for https://pypi.python.org/pypi/zs/", and every
time I've sat down and spent a few hours trying I've ended up utterly
defeated with a headache. Distutils is spaghetti, and Windows is
spaghetti (esp. if you've never used it for more than checking email
on a friend's laptop), and the toolchain setup is spaghetti, and then
suddenly people are talking about vcvarsall.bats and I don't know what
all. I honestly would totally benefit from one of those
talk-your-grandparents-through-it tutorials ("here's a screenshot of
the dialogue box, and I've drawn an arrow pointing at the 'ok' button.
You should press the 'ok' button.")

I think the SDK covers both 32 and 64 bit? If so then leaving visual
studio out of things entirely is probably simpler.

I'm also unsure how you even get both 32- and 64-bit versions of
python to coexist on the same system.
