Fair enough.

Turns out that Matthias asked me the exact same thing for the first time
wizard (it was supposed to be added to the control-center, but made more
sense in GDM).

This is where it would be used:

Note that the code itself is GPL, no LGPL.

Matthias was interested in adding key navigation to it as well.

You guys can hash out what you need the widget to provide. I think it'll
probably be quite cumbersome to move, depending on whether you just want
the map widget, or the selection bits as well (the drop-downs we have
now are not the best, and I completely failed at trying to use
libgweather's location entry instead).
