Answer 1

You won't be able to install PyGObject like that because MS Visual C is not going to be able to compile it.

If you follow the PyGObject Getting Started in Windows instructions, you should be able to install PyGObject in Windows using MSYS2.

1. Go to http://www.msys2.org/ and download the x86_64 installer
2. Follow the instructions on the page for setting up the basic environment
3. Run C:\\msys64\\mingw64.exe - a terminal window should pop up
4. Execute pacman -Suy
5. Execute pacman -S mingw-w64-x86_64-gtk3 mingw-w64-x86_64-python3 mingw-w64-x86_64-python3-gobject
6. To test that GTK 3 is working you can run gtk3-demo
7. Copy the hello.py script you created to C:\\msys64\\home\\<username>
8. In the mingw64 terminal execute python3 hello.py - a window should appear.
