Show HN: Proton a Pure go, no CGO GUI library for building applications

- **Proton** is a new GUI library written entirely in the Go programming language ("Pure Go"), with no dependency on C or CGO (a Go tool that bridges to C code). This makes it easier to compile and distribute cross-platform apps. - Most existing GUI toolkits for Go (like GTK, Qt, or SDL bindings) require CGO, which complicates builds, increases binary size, and limits cross-compilation. Proton aims to avoid those headaches. - The library is currently in early stages — the author submitted it to "Show HN" (Hacker News's platform for showing off personal projects). It's notable because a pure-Go GUI could simplify desktop app development for Go programmers, but it likely lacks the maturity and widget set of established toolkits.
