Could not import the zenmapGUI.App module: \'No module named gtk\'. I checked in these directories:
/usr/local/bin /usr/lib/python2.7 /usr/lib/python2.7/plat-x86_
Same issue. I notice that in kali 2019-4, in the path usr/lib/python2.7/dist-packages/gtk-2.0/gtk there are some init files, perhaps they are needed by the zenmap GUI.
