Kinda, sorta.
You can certainly (have someone) build a BMX wheel around a fixie hub.
I suppose you could somehow disable the freewheeling action of a regular hub too, but I wouldn't recommend it. Putting back pressure on the pedals on a bike that hasn't a real fixie hub can cause the sprocket to unscrew.
It'd be a fairly strange BMX if it has a gear shaft. Most "real" BMXes are single speed, their driveline consists of cranks, a bottom bracket and the rear hub. No gear shaft there.
Two, but this is not the same as how many speeds the BMX bike in question has. A BMX bike has a sprocket in the front, and a cog in the back and each is a gear, but is considered a single speed bicycle because two gears and a chain are required for transmission of rotational force from the crankset to the rear wheel.
