If I understand you right, you want this page: http://pokemondb.net/move/all
It is found by going to "Moves" in the menu at the top, then clicking "All moves". It's not updated for the new Black & White games yet (might not be until English names are confirmed).
Then click the move name to see which pokemon learn it.
But if you want the opposite, to see the moves that each pokemon can learn, you look in their pokedex. Go to either "Pokemon list" or "Pokemon with stats" in the menu then click the pokemon you want. Their moves are on that page.
