when are they going to make a “wheel” shaped spacecraft so they can artificially create at least SOME gravity

Likely right after someone invents a frictionless material for the huge bearings that will be needed at the hub of such a "wheel".

Are you assuming the need for non rotatating center core? What need is there for that? Given a slow rim speed, a fixed central core would barely register as moving, no?

Of course. But what good is a slow rim speed? The rim woul;d need to move quickly enough to generate the needed force to simulate gravity. There would need to be a hub and there will be friction.
