GUI managed firewall linux distros

[Technomage-hawke]

ok,
I am seeking a low footprint GUI capable firewall distribution for the room 
mates here (something that looks a lot like whats on a linksys router or some 
such) that can be managed by someone not very smart about linux.

I may be moving soon and would rather not leave my mates in a lurch when it 
comes to internet security.

suggestions?
