Thanks for your hint, Nils!

AFAICS, Wicd is a GUI tool, right? This does not play well with the
"configure my systems automatically" part of my original post. Automatic
configuration is best done by editing config files or running non-interactive
scripts or something. Interactive configuration (as it gets more and more
popular in new disros :-( ) is a big showstopper for automatic configurations.

Hmm, AFAICS, wicd can also handle wired connections, so why would it not be
able to shut down wlan when wired comes up?
