How to answer 1.e4 e5 2.d4?

1.e4 e5
2.d4 exd
3.Qxd Nc6
4.Qe3?? Bb4 wins the Queen so no need for g6, which certainly doesn't deserve an exclamation mark.

Of course u meant Qc3 but really, this is not the reason why Centre Game is not so good...
We could say white is lost after 1.e4 e5 2.d4 e5xd4 3.Qxd4 Cc6 4.Qe5 (check!) Nxe5, but what would be the point? Anybody is lost if u make them play blunders.
Seriously, I used to play it as white but i have issues with this line :

In the line after 1 e4 e5 2 d4 ed4 3 Qd4 Nc6 4 Qe3 Nf6 5 Nc3 Bb4 6 Bd2 O-O 7 O-O-O Re8, the move 8 Bc4 certainly seems better than 8 Qg3, though it only gives White equality. After 8 Qg3, 8 ... Rxe4 seems better for Black than 8 ... Nxe4?! 9 Nxe4 Rxe4 which gives White some compensation after 10 c3 (ECO C 5th edition, MCO-15, and I think NCO also, give approximate but unclear equality after 10 ... Bf8, but don't address 10 ... Be7 so maybe there is some new theory which supersedes). The reference books just cited give White equality in the line after 8 Bc4 and approximate but somewhat unclear equality in the 8 Qg3 Re4 line (as well as 8 Qg3 Ne4). That said, the latest reference books I'm aware of don't seem to have been updated in the last dozen years and online material (which I haven't researched) seems to be making it uneconomical to do so, though I'm a book person myself and prefer that medium.

The title says it all. I've got a friend who tends to play a lot 2.d4 after a King's pawn game. Right now I have not find a nice way to decline the pawn, and I don't like 2...exd4 3.Qxd4.
Any Idea that does NOT involve the Scandinavian, the French or the Sicilian? (If necessary, I'll swap to the Caro-Kann, but please not one of the 3 openings listed before!).
These are some of my first ideas, but I'm sure they are not correct, as I always end up with some small problems.
