I'm actually working on that - it's called Hypen - (hypen.space).

You can build your core in Go or any other supported language, and write the UI in the Hypen DSL.

While desktop is still in the works and should be out in the next week or two, currently the alpha supports Native iOS, Android, Web and Web Canvas, and just like mobile, the Desktop will be _real_ native.

Thanks, I will keep an eye on this as well. Wish you success!
