Ideally, I'd like it if they had a past together, but I'd give that up to give Sam and Sharon their due.
But then, why use Natasha at all? If she just knows about Bucky's past, that role can be filled by Nick Fury, Maria Hill or Sharon.
As a Russian spy, Natasha would logically have a lot more inside info on the project than SHIELD would. So even without a love interest there, Widow is still naturally the heroine who'd be most likely to have a line on Winter Soldier.
