Version 0.9.3 of Fettuccine is now moving into extras-devel; with this one, I've put together a minimal user interface for operation as a widget. There are overlay controls to navigate forwards and backwards through the list of webcams, as well as a label at the bottom of the widget with the name of the webcam. These controls can be switched on or off via the webcam options dialog box.

Also in this update, the default list of webcams has been improved (and you can reset the app to this default list now from the "Import Webcam List" menu option). And, a bit more work on authentication has been added; you should now have the option to continue loading a webcam image, even when SSL errors occur.

I'll append a screenshot of a widget with the new overlay controls:
