PCgen software includes a small compendium of stats without any of the fluff for earlier editions. Basically its just information taken from the free SRDs of D&D. it didn't have any information for D&D 4th ed. but if you have some time there is a tutorial where you can set up your own reference compendium.

Fair warning, I never actually used it for a session. just downloaded it for a game that never happened. So I don't know from experiance how convieniant it is. but it seems like this is what your looking for.
