Java2Script is mainly focusing on converting SWT desktop applications. And WindowBuilder Pro is sure a professional GUI designer to help developers building SWT desktop applications. As from earlier trials ( http://j2s.sourceforge.net/screenshots.html#swt-designer ), I found that SWT Designer is a great tool to help designing SWT applications. In order to improve our development efficiencies, I decided to apply for a copy of WindowBuilder Pro instead of limited trial versions. And Eric Clayberg of Instantiations is very kind to give a quick reply and is very generous to donate WindowBuilder Pro to Java2Script team.
Thanks Instantiations Inc. I think WindowBuilder Pro will help us working more efficiently and improving Java2Script plugin to a higher quality level.
