...The README notes that GTK development packages must be installed (e.g., libgtk2.0-dev) to build the examples. Go-GTK has over 1,100 commits and shows a serious commitment to bridging Go with desktop GUI frameworks. Because it ties into GTK's C libraries via cgo, it enables event-driven UI programming in Go rather than being purely browser/web based. This makes it interesting for developers who want to build cross-platform desktop applications in Go with the look and feel of GTK. License is BSD-3-Clause, which is permissive.
