The front end is openlayers. http://openlayers.org If you want the versioning stuff then you need 1.6-beta3, with versioning enabled on a postgis versioning backend. It's still pretty bleeding edge functionality. But for the front end openlayers is the best route forward, we've added some stuff there that makes WFS-T work a lot better.
