Vala Doc

it's funny how things just pop up on your radar and seem to serve the purpose you are looking for, it's all written in C but some of the elements look relatively easy to mock up a look and a layout, as it's cross platform, you can run on mac, pc or linux!

Vala is a programming language using modern high level abstractions without imposing additional runtime requirements and without using a different ABI compared to applications and libraries written in C. Vala uses the GObject type system and has additional code generation routines that make targeting the GNOME stack simple. Vala has many other uses where native binaries are required
