Are there any good UI/GUI libraries out there?

I'm maybe going to program a three year long project for my masters degree in IT. We are still thinking on which language/libraries we will use. My group and I love rust but the only thing that is really bothering us is that we can't find a good UI/GUI library out there.

The project will be a tool, so the UI will look like Photoshop, Jetbrains, Blender, Unity, etcSo I'm asking here, thanks in advance!
