Not using Charm, but I've designed a TUI Gemini client in Go! It's pretty popular, for terminal clients at least.

I miss a search function, but thanks for your client. I may write one a la av98, but with jimtcl instead of Python3. It makes really easy to write networked stuff, either with TLS or not. I wrote a finger client in minutes.

Aren't Gemini pages static-by-design? It would be hard to do something really interactive / state-preserving with them if I'm not mistaken.
