That was kind of a dick move when that wasn't even what they were asking.
OP has pokemon on the Dream Radar app but no copy of Black and White (2) and therefore cannot get the pokemon in their game and use the poketransporter+bank like normal. I assume they are looking for a way to extract the pokemon from the Dream Radar app with just their 3DS and a PC. Then inject them into their game with PKHeX. If I'm wrong I apologize but that's what it seems like they are asking. AFAIK, there isn't a way to extract pokemon from the app without the game. I'm not sure if a HomeBrew exists that does it. If you can't find one, you could probably ask around the devs that work on things like PKHeX or PKSM and see if it can be implemented somehow.
