Right now you're options are pretty much Softimage, 3DS Max and Blender but if the FBX->GLM converter gets finished you could pretty much use anything since just about every 3d app has FBX support. Rich Whitehouse is also working on his Noesis model view to allow converting to GLM/GLA which can import just about any 3d format but it's not working quite right yet it seems. Try a few programs out, see what you like. I've been trying to dig up the old Maya dotXSI exporter but unf...

unf?

Are all these programs free?

the "unf" is because he reached the character limit for the comment, so it cut him off even though it had let him type more.

But no, Softimage, Max, and Maya all cost very large sums of money.
