Thanks Phil. It wasn't on PATH (I assumed that passing "--qmake 
C:/Qt/Qt-5.11.2/bin/qmake.exe" to configure was enough), but now that it 
is, everything is working great; success at last! Kyle spotted that I 
had written PyQt.Core instead of PyQt5.Core, but this was only a typing 
error in my email and correct import statements were not working either. 
Now they are and thanks again for your help.

Best regards,
Tim
