Hello,
I'm super happy to see that some folks are trying to make apps with Golang.
I'm myself the author of a Go package to build GUI with WASM and Go => https://github.com/maxence-charriere/go-app
WASM give us an incredible amount of new possibilities and hopefully, we will get to a point where Go will be used in production also for GUI/apps purposes :)
Congrats for this and good luck for the future.
