GUI is definitely an open problem in Rust, but to be fair, cross platform GUI is hard. In all of programming, it seems that Qt is about the best that we have when it comes to cross platform GUI, and I don't think most Rust developers care enough about Windows to write and maintain native Windows-only GUI libraries. C# (or I guess F# or any of the other .NET languages) is definitely a better fit for Windows UI programming.
