I think KNetworkManager does support the full settings D-Bus interface
as a user settings service.  nm-applet does not because there are/were
security concerns allowing random programs to read/write network
configuration.  But yes, you can write a complete network connection to
GConf even using "gconftool-2 --load <xmlfile>" and get a network
connection.  Adding passwords to the keyring is a bit more complex and
would involve using Python or C and talking to the gnome keyring daemon
(though I hear they now have a D-Bus interface too).
