Well as far as I know after:
1. e4 e5
2. Nf3 Nc6
3. Bc4 Bc5
4. c3 Nf6
5. d4 exd4
6. cxd4 Bb4+
Then White's options are:
1. Enter the Greco attack with Nc3, which has been analyzed to death and leads to a forced draw. The main variation's like 20 moves long.
2. Nd2 loses the e4 pawn.
3. Bd2 leads to another equal position after 7. ...Bxd2+ 8. Nbxd2 d5, destroying White's centre (but it does not lose the e4 pawn, because after 7. ...Nxe4 8. Bxb4 Nxb4, White can play Bxf7+ followed by Qb3+ and Qxb4 to win the pawn back).
I know the line 4. c3 Nf6 5. d3 O-O 6. b4 Bb6 7. a4, gaining queenside space has been somewhat popular lately, but I haven't played the Giuoco Piano for quite a while. It's a rather boring opening too, in my opinion >_<
