With OS X Lion on the market, we see that Lion is only compatible with XCode 4, then I'd like to know if the project generated by GLBasic is compatible with XCode 4 and there is no problem at all using it.

Yes. You get a lot of warnings about stuff being soonish deprecated, but it's OK. The problem is, that my compiler sets some CPU information, but you should not worry I think.
