Compiler error while installing py-bcrypt in Windows 7
These libraries are already compiled and available somewhere. Someone already uploaded compiled versions for windows. I was able to run flask-bcrypt in Windows with the files.
You just throw it in your flask/scripts/python packages folder.
It was answered in the Flask subreddit with a location to download the libraries you need:

Have a loot at these MinGW binaries. It should be a version of MinGW GCC specifically taylored for building Python extension modules.
this installer tries to fix all the problems with compiling Python distutils extensions with GCC
