The Eclipse platform is great for making large, complex GUI apps, and IBM aren't the only ones using it by any means. Startup time is slow (for starting development as well as launching the app) but you can develop an app with a very responsive interface (which is apparently impossible in Swing.) Eclipse RCP is definitely a good batteries-included application platform for heavyweight GUI apps. I wouldn't use it for something small and light, though.
