     I'm not sure I understand completely the point, but it is possible 
to configure different
wifi stations with either static or dynamic addressing in 
wpa_supplicant.conf. In the section
of a given station, you can specify an interface name, which defaults to 
"default", and then,
in /etc/network/interfaces, you can have a section for each of these 
names, some static, and
one dhcp. Sure, there is no tool to help you writing 
/etc/network/interfaces, only your
favorite text editor. Actually I didn't check if wpa_gui was offering 
this feature.
