For our User Interface Design class we've been working on a flight planner application to allow recreational pilots and aviators to quickly and easily create a flight plan. The web technology of choice? Right now it's the Google Web Toolkit. The rich web interface tools GWT has available are powerful and easy to use. After all, it's just programming in Java... with some added CSS of course. We've discovered an extensive add-on library to GWT called GWT-EXT. This toolkit has the power to turn your browser into a truly rich, desktop-like environment. There is a full demo showcase, with sample source code and all.
Window managers, dynamic history support, custom tabbed panels, layout managers... this is really sweet stuff. Our project is still in the prototyping stages, but within a few weeks a concrete interface should be available for your viewing pleasure.
