It seems lately the Holy Grail of game GUIs has been Flash. Scaleform is an example of a commercial GUI based on Flash. This does not work for indies because of the cost.
Hikari is a great option for Ogre users. It was just released yesterday and I already have it integrated into Zero Gear. It is still new and needs a little work but thanks to it being open source (LGPL), we should start seeing a lot of support from the community.
P.S. One thing to mention is Hikari only works on Windows.
