问题
I am writing a Python2.7/PyQt4 programm under Ubuntu, but the application will be deployed on a Windows platform. One of the functions is that the application should capture several keystrokes (e.g. "Alt+A") even if it is not in focus/minimized. I use PyGlobalShortcut for this purpose, which is a Python/SIP wrapper around libxqt. Following the manual, I installed Qt4 + SIP and ran the pip install PyGlobalShortcut command, which automatically compiled and installed the libqxt library and the Python wrapper. This worked flawlessly.
Building natively under Windows
However, I hit the wall trying to install PyGlobalShortcut under Windows. The binary distribution for the package is obsolete, meaning I have to compile it myself. I had to install Qt4 + MinGW and tweak $PATH, which was not a problem. Next step is to get SIP, which is unfortunately not provided in a binary form for Py2.7. I got the source code of SIP, but was not able to build it:
sip-4.17 $ python configure.py --platform win32-g++
sip-4.17 $ make
make calls for mingw32-make which immediately returns with an error that MSVCR80.dll could not be found. I googled a bit and it seems that it is a component of MS Visual Studio or something like that, but what does it has to do with MinGW? I was not able to find any kind of official web site that provides this dll or explains how to get it.
Cross-compiling under Linux
I also thought that may be I could cross-compile PyGlobalShortcut on Linux machine using MXE. I did not manage to do this as well.
I used this SO answer as a guidance. I've got MXE, cross-compiled Qt4 and checked with wine that it works. Then I included <mxe>/usr/bin and <mxe>/usr/i686-w64-mingw32.static/qt/bin into $PATH and tried to cross-compile SIP for windows. It failed miserably because Makefile called for native linux g++ and not for c++ compiler of MXE:
sip-4.17 $ python configure.py --platform win32-g++

So I symlinked compilers and linker under <mxe>/usr/bin, i.e. i686-w64-mingw32.static-g++ to g++ etc. This helped, but now g++ requires Python libraries and headers. It looks for them under /usr/include/python2.7 - but they are compiled for linux and therefore cannot be linked to windows binaries.

It seems that I need a Windows build of Python to compile this stuff, placed under <mxe root>, but... Come on, now it's getting way too complicated. I'm pretty sure that I am missing something simple here. Unfortunately I don't have much experience in compiling for Windows and would appreciate any help.
Other options for shortcuts?
I do not mind to rewrite my Python program and use any other cross-platform library to catch global shorcuts, but I did not found any other except PyGlobalShortcut.
