I have been able to install MiniWord under Windows. It is a bit more challenging.

You should use cairocffi instead of pycairo:

  pip install cairocffi

You also need to install the Cairo DLL. The easiest way is to install the full GTK3 runtime from: https://github.com/tschoonj/gtk-for-windows-runtime-environm...

You must add the directory containing libcairo-2.dll to your PATH environment variable. In my case, this is:

  C:\Program Files\GTK3-Runtime Win64\bin

Note that MiniWord is not yet optimised for Windows. While it mostly works, the rendering quality is lower and startup is slow.
