Feel free to use mine as a basis.
For all of those who want to try making mokups, you may be interested in the current state of art:
EQ 2, probably the most complete LFG interface existing (being able to search by role instead of class):

VG SoH shares the same system. Note the ability to set yourself to LFG for lower level groups with the mentoring check (mentoring is what FF11 players call synch).
The DDO interface is well worth mentioning too (but it's simpler since there is only one role per class):

Due to the grouping required nature of the game, the interface is always used and full of groups. I'm pretty sure LoTRO has a similar system.
Interestingly WoW interface is not really well done (at least last time I checked) and Rift doesn't have any interface at all. But those two balances the problem with automated instance finder (and/or zone/level specific channels used for LFG/LFM).
I have never played Aion and would be glad if someone could tell us a bit about its LFG system.
I'm pretty sure we can work out a nerly perfect tool for FF14, then it would only be a matter of spamming it until SE notices... as usual.
