There's a really good UI framework for Clojure (not ClojureScript) called seesaw. If I recall correctly it was swing, but it's a very nice data focused, functional library. It really works well with the Clojure philosophy and interactive development. It's also VERY complete.

There are downsides, however. The UIs that it creates definitely look like Swing apps. I.e. ugly at least on Linux. Also, the up to date documentation is difficult to find, I'll like to it here when I get home. The GitHub-linked docs work fine, but they do miss a few features.

Seesaw/swing are the old stable solution. The latest library is cljfx built on JavaFX. The developer is very responsive and open about it's development

It's all React-like. You have a state atom and a GUI map data structure (which I think is equivalent to your DOM in React..) and then you hook up events that update the state and blah blah. It's all very clean and easy to read/use. The underlying JavaFX is also great for an OO GUI library so it's not gross to dive into if you need it

For frontend Reagent (React but with just Clojure functions and data structures. No classes, no jsx, just one language and immutable data.), and re-frame which does state management and event dispatching better than the competition. Redux is a poor poor imitation.

For web frontend (ClojureScript) there's reagent and re-frame, the Clojure versions of React and Redux.

There is a swing example on the getting started page (or there was a few years ago). It was a one liner to have a Swing pop up say "hello world" or something like that. I'm not sure how easy it is to write actual apps that way.
