[Gambas-user] Is GTK still relevant?

[Bruce]

This is just a general question. Does anyone out there actually use a 
GTK based UI?
I don't know because we have used the gb.gui.qt approach for several 
years now. However, today I tried to do a bit of web research about GTK 
and failed to find anything that could justify the effort of trying to 
use it as a general user interface.
I did find some stuff about GTK4 but it seemed to be, well, take some 
chrome off and add some more chrome over there. A bit like 1950's 
Oldsmobiles.

Any coments?
