Not really. Quite some more "else".You wrote:

"And for others that also don't know, a great example on how to do cool UIs with Java"

This is vague, and could mean either it's a "cool GUI app (end-to-end) in Java" or "cool GUI app (with just the GUI) in Java".

Think how one could say the same thing you said for a 100% Java app too, e.g. "jEdit/NetBeans/etc is a great example on how to do cool UIs with Java".

I added the explicit information that the Java part is constrained to the UI, and clarified what the backend is written in.
