No. All you need is the Wii hardware, a DS, and the Pokemon games from both systems.
The DS uses wireless linkage, so you just have to turn it on to link up. There should be an option to Copy your DP Pokemon over to PBR on the Wii. Likewise, on the options menu at the beginning of the DS game, there will be an additional option while you have this Copy Feature activated. I believe it's called "Wii Settings" or something like that.
