Is there anyone working on cross-platform GUI for Elixir/Phoenix?

I want to build a menu app on macOS for me and my friends. I know neither Swift nor JS. I only know Elixir, which means I would have to learn JS to be able to do this.

It would be cool if cross-platform was available in Elixir/Phoenix. Is anybody working on this?

Check out wx that is distributed with OTP.
