I spent a couple years on a Java Swing project and hated every minute. Karsten Lentzsch provided the only saving grace with the JGoodies libraries and seesaw supports the JGoodies Forms.
I just started writing some Clojure in my free time and I hadn't looked into GUI toolkits yet, but this definitely provides a great jump start. Bringing enlive's selector style to Swing widgets will make life livable again.
I think if you have to work with Swing, you definitely have to go with the Netbeans Swing GUI Builder. I have worked in some Swing projects and it has been a joy to use. It comes out of the box with the IDE.
Among other things, Seesaw 1.3 will hopefully have friendlier support for pulling in UIs laid out with UI builders (NetBeans, the Google one in Eclipse, etc).
