Lever: a programming language with built-in support for GUI and OpenGL

If you want to see really easy to use native GUIs, look at Red/RedSystem. The runtime manages to be both very high level and tiny. It is basically a reworked Rebol with a built-in system language DSL that allows you to compile miniscule binaries. It's still in the early stages though.

It seems like it's targeting gamedev and virtual reality. But it's not likely going to see much use of it's slower than Python.

Trying to implement asynchronicity using an explicit event loop is a tried and failed approach. Look at asyncio in Python, for example.

Async/await is a little verbose, but async/await-native efforts like curio and its little ecosystem are the future.

It seems an implementation using the pypy runtime might be a better idea.

All that said, with Vulkan here and parallelism in general being the way of the future, Python with its GIL limitation seems an odd choice.
