Why they would want a GUI for an automated process I don't know. I believe there are GUIs out there, though. Google should provide.
The email part is easy, though. To be emailed a summary of what happened during an rsync session, just redirect the rsync output to mailx. I'd use the '-v' rsync option to see what's going on, e.g.
rsync -v /patch/to/source target:/patch/to/destination 2>&1 | mailx -s "Backup summary" email@example.com
adjust to taste, obviously, but you get the idea.
