Yes, people can try to build as they want, that's the beauty of open
source :) But for official distribution, I don't want to depend on non
free software (outside windows, obviously). I need a process to build
numpy in a reproducible and in a hassle way (well, as much as possible,

This has nothing to do with fortran per se, but with the fact that MS
keeps breaking the standard C runtime. Hopefully, with python 3, this
may not be an issue anymore (python on windows won't use the standard C
API, but windows API instead, because MS guarantees ABI in this case, at
least that's what I understood).
The fortran compiler has to be the same to build everything, but python
does not use any fortran, so you can choose whatever you want as long as
you use it for everything (BLAS, LAPACK and numpy).

BLAS/LAPACK is built with fortran, and python with C compiler, so no :)
What may be important is the C++ compiler to build (more exactly to
link) python if you build python by yourself, but I don't know how this
works on windows. I just build softwares for windows, I don't use it.
