How hard would it be to add a GUI to this? I don't think I've seen a lot of GO Gui implementations in the past
My personal favourite is an ImGui wrapper https://github.com/AllenDang/giu
The most featureful is probably unison, although I'm uncertain if anyone uses it outside of their own project (https://gurpscharactersheet.com), meaning documentation will be sparse https://github.com/richardwilkes/unison
Gio uses a different way of thinking about GUIs, used by Tailscale and gotraceui https://gioui.org
Wails is great if you're familiar with development on the web https://wails.io
The GTK4 bindings also look nice https://github.com/diamondburned/gotk4
Cogent Core also looks neat, but I didn't have the time to play with it before I switched over to using the Odin programming language instead of Go https://www.cogentcore.org/core
I personally had nothing but issues with Fyne (especially in regard to performance, across multiple computers and operating systems), but it's probably the most popular option https://fyne.io
Last week I came across these Qt bindings: https://github.com/mappu/miqt
I have no personal experience with it yet, but am excited to try it out.
