No, sorry. There's no possible way to transfer Pokemon from Gold/Silver/Crystal to Diamond/Pearl. You can, however, transfer Pokemon games to the DS with the following: Pokemon Ruby Version Pokemon Sapphire Version Pokemon Leaf Green Version Pokemon Fire Red Version Pokemon Emerald Version That's it. I hope you found this useful.
