Technology choices revisited

In one of my earlier posts Technology Choices I had looked at what user interface toolkit I should be using. What I've discovered in the intervening time is that this application is going to put a premium on flexibility in presentation. As a result, I am seriously reconsidering the user interface toolkit. The Eclipse RCP is a very powerful platform upon which to build an application. Unfortunately it does have a very strong set of metaphors upon which it is built (Views and Workspaces) which seem too rigid for what I am attempting.

So I am seriously looking at using QT with the Java bindings.

Any thoughts?
