There is [https://forum.nim-lang.org/t/5759#35698](https://forum.nim-lang.org/t/5759#35698)
And my NEd editor and my chess game. And of course Aporia. Aporia is still GTK2, and NEd is still oldgtk3. The other two are gintro based.

I myself am working on a vector drawing app, some sort of port from Ruby, but with low intensity. But my general recommendation: We have nearly a dozen GUI tools for Nim now, try them first, and come back to GTK when all of them fail only.
