My apologies for missing this before opening bug #31123, which should solve the nethack menu issue more generally.
Separately, the GTK2 port is better handled upstream (it's very involved). There was a project to work on this at http://gtk2hack.sourceforge.net/index.html, but it hasn't been updated in a while. Some people also like slashem, which is a fork, currently using GTK2.
