I don't think I'd call Rust user friendly.

If the problem is the type system/borrow checker, it's simply a question of experience.

Not when writing GUI like code, to the point that the Rust team acknowledges that additional work needs to be done after NLL lands on stable.

So while Rust is much more productive than ATS or Cyclone, there is still room of improvement for that experience.

There's always room for improvement, but speaking of GUI, gtk-rs is pretty usable already.

It is, if you don't mind sprinkling your code with Rc<RefCell<item>> everywhere, as means to access widget struct members in callbacks.
