I would have to strongly disagree that QT is a good idea for clojure development. I have posted about this several times before but I find that QT isn't ready for heavy java dev just yet, at least on the mac.
1. QT jambi will not run on the mac unless you are using java 1.5. This is because QT is using the carbon API below to implement its interfaces and the mac version of java 1.6 doesn't support the carbon API, it is 64 bit which means you are going 100% cocoa. So no java 1.6 for you. 2. QT's event handing is very sensitive to threading issues. This boils down to when you are developing from the repl you will most likely get hangs. You have to use odd options on the java invocation or your process will hang permanently. 3. Forget about openGL with QT, at least on the mac. Running any JOGL (or lwjgl) code starts an initialization system that fires up some swing threads. If you are running from the repl, you can bet this will hang your machine due to #2 above. I am not certain what other situations will hang but I assure you it is irrecoverable when it does. I believe you can create very good looking applications with swing, builder or otherwise as many people have done so (not that it is easy). I do believe a builder is a giant step forward but only if you have a design team that you would like to separate from your coding team. If it is just you, then a builder really doesn't add that much. Both systems allow separation between view and model or any event system you would like. So that is a non-issue. The points I have stated above very much are issues you will have to take care of. One thing I think would be useful for clojure would be clojure.contrib.swing that has functions that create various callback listeners just from a function (wrap the proxy generation) and such, as well as various macros I have written for dealing with GridBagLayout etc. If you decide to go this way you should let me know as I would like to show some of them to you and perhaps we could start the process of formalizing them into clojure.contrib.
