I just happened to build a little project using Slint (https://slint-ui.com/ https://slint-ui.com/) last week and found it fairly pleasant, even though it's got some rough edges still. I liked it because I was able to cross-compile to Windows from my Mac and from my Linux based CI with extreme ease ("cargo build --release --target x86_64-pc-windows-gnu"). It supposedly has some sort of native widgets available if you have Qt installed, but I haven't pursued that yet. It has a little meta language for describing the UI that gets compiled when you compile the code and that was nice because it catches type and syntax errors at compile time. I almost went with Tauri, but the cross-compile story didn't seem quite as good compared to Slint. Tauri does look nice though—web UIs are more flexible than Slint at this point. But for my simple little tool, Slint really hit the spot.
