Two GFCI outlets on the same circuit, just for code?
Just connect the cable from the second outlet to the "line" side of the first GFCI (or wire-nut and pigtail the first GFCI. Then install the 2nd GFCI normally. 

Alternatively, most GFCI outlets come with little stickers to put on the cover plates of downstream protected outlets.   If you choose that route, you would wire the cable to the 2nd outlet to the "load" side of the first outlet.
