Is anyone working on direct Qt bindings (I don't consider using PyCall a viable option). Qt is a bit harder to wrap since it is C++, but it look like Lua has been able to auto generate bindings based on the Qt headers.
Keno Fischer, who recently created the Cxx package [1] used to be a Qt dev, so I wouldn't be terribly surprised if we see such bindings materialize in the future, using Cxx, of course. That said, I don't want to speak for him, so if someone wants this, they should maybe go ahead and start working on it!
