I have used Qt a fair bit for hobby projects, and quite like it in the context of cross-platform C++. But I haven't yet wrapped my head around what a Rust interface to Qt would look like, and results searching https://crates.io for Qt bindings had kinda scared me off.
https://github.com/KDE/rust-qt-binding-generator looks quite interesting though!

Ha! Well, at least we don't have so long to wait, I guess.
