Hi Timothy,
I took an extremely similar approach in this project
<https://github.com/jfacorro/clojure-lab> using Swing as the underlying UI
toolkit. Components can be described using a hiccup like syntax, although
they are actually represented as maps in the end. Since the UI is mutable
by nature the root component (an immutable map) is held in an atom.
Before building this abstraction I considered implementing something like
the React approach, but at the time it seemed like a lot of work and I was
not convinced it could actually work since I hadn't heard of React back
then. I think pursuing the same approach with a desktop UI toolkit would be
an interesting project.
