> There is 0 Erlang-native GUI libraries

Have you seen ex11? [1], it's Erlang native, and at least 0.1 of a GUI library. X11 and Erlang actually go together really well, although a lot of important functionality for a real application is missing; I used this to display images generated by an Erlang application, and it felt a lot nicer to me than using wxWidgets; I added a few bits of functionality to the library while I was in there, and it wasn't that hard to turn the X11 protocol docs into Erlang code for the things I needed.

I imagine if someone had a real need here, it wouldn't be that hard to get it into shape. Caveat: X11 is dying, etc.

[1] The most active fork appears to be here https://github.com/skvamme/ex11 -- it's been somewhat retargeted to mobile, but the examples for desktop should still work as well as they did.
