I think GConf is a good place for that:

Yes, in the "Developing control panel applets" section:

http://maemo.org/development/sdks/maemo_5_examples/

I believe this is a HildonTouchSelector widget:

http://maemo.org/api_refs/5.0/5.0-final/hildon/HildonTouchSelector.html

Check out one of the Hildon 2.x tutorials. You might also want to go
the Qt route. I don't know if you can write a control panel applet
without any GTK+/Hildon code, though. I'm sure there are some
community control panel applets in the Extras-Devel repository. If you
want to go the Qt route, you can just make it a normal application
that appears in the application list, and not in the control panel. Or
you write a thin "wrapper" for the control panel that simply starts
your Qt application when activated.

HTH.
