The organization behind QT (QT Group) has pretty onerous licensing terms.
My understanding is that it's $3,950 per year just to develop using their libraries on your own computer if you ever in the future intend to commercialize a product using QT. Transitioning from the open source license to the commercial license is something you can do but it's not the happy path and their FAQ seems to indicate that it comes with some sort of penalty.

Something like Slint (Rust based but includes CPP and JS bindings) is not as comprehensive (yet) but it's more modern and the licensing terms are significantly more in line with software industry norms.
GPUI from Zed is also something to monitor: https://www.gpui.rs/
Also, in general you can find an extensive list of Rust-based native UI libraries here: https://areweguiyet.com/
