I'm a bit late to the dicussion, I know! (At home on a dial-up connection at the moment, and it's not exactly conducive to forum surfing.) Anyway....
In my opinion, Wesley definitely wanted his mother to get together with Riker in
Encounter at Farpoint. Think about it: he's fifteen, he hasn't had a male role model around, and all of a sudden he meets the cool, heroic Commander Riker. Who wouldn't want Riker as a stepfather? Better than that stiff, boring Captain Picard, at least.
It is clear from the start, though, that Beverly is *not* interested in Riker at all. This is confirmed in "The Host," when she is pretty aghast at the idea of Odan being in Riker's body. When she is discussing it with Deanna in Ten Forward, she almost shudders.
So the relationship that they do have is more of a brother/sister one, although I agree that there is a LOT of touching in season six. Beverly and Will are probably the two most tactile people on the crew, so it makes sense that they would touch each other casually, I suppose.
Having said all this, I can imagine another version of TNG where they were interested in one another. Riker is much closer to my idea of what Jack was like than Picard is. And, as
mon capitaine said, he is certainly more like Beverly personality-wise. I wonder if they were ever intending to do something with Riker and Crusher in season one, or whether the scene in
E@F was just a throwaway? Because it would have helped slow the P/C thing down a little bit (which would have been a good thing IMO, given that it seemed like they were on the verge of getting together for virtually the whole season) if she had also had a flirtation with Riker.
