There are tons of really good Eclipse plug-ins out there. But a really good GUI builder wasn't available so far. This has changed with the WindowBuilder proposal in December 2010, announcing the relocation of the famous (and formerly commercial) Eclipse GUI builder plug-in to Eclipse. WindowBuilder is now an official Eclipse plug-in, finally making available a really great GUI builder for Eclipse. And the first incubator release (version 0.9.0) is already available for download. Don't be afraid by the incubator icon, every Eclipse code donation has to start as an Eclipse incubator project. Time to download and install this plug-in right away!
