My impression is that a rotating wheel space station, while theoretically well within the grasp of current engineering ability, would be extremely expensive given that we've never done it before.
You could imagine a system where you 'space elevator' objects and people via the connecting cabling, whilst pumping fluid to offset the mass. You would likely want each side to be manned by two people.
You could later add more modules if designed correctly too. They would likely approach and attach to the centre (in a pair, one either sude), match the spin and then slot into their respective 'slots' and rotate on an arm.
