I tried it and It sort of works. You have to launch it from applications menu and it doesn't come up in the widget list. I had a quick look at it and noticed 2 things that may prevent it from working correctly. 1) It installs the desktop file in the wrong path (should be in /usr/share/applications/hildon-home/) and 2) it's not compliled as shared object like the other desktop widgets. Changing the install file path alone didn't fix the problem so I recompiled the example as using lib template and edited the desktop file according to documentation here. The widget is now listed in the widget menu but it cannot be started (Error loading module). I'm thinking it needs some changes in the code in order to get it working as a proper desktop widget (I haven't looked how it's implemented yet). I'll try to get it working some time this week if I have some free time to spare. I suggest that you join the maemo qt4-devel mailing list. You can get answers to development related questions faster there.
