The most difficult part here is making the wall strong enough so it doesn't
wiggle. Normally such a wall would be anchored below the floor, with at
least the end being bolted to floor joists, if not more. Other than that,
it would be built much like a standard wall with studs 16" on center, and a
top and bottom plate. Double top plate and maybe 2x6 rather than 2x4 might
add some strength.

Yeah, that's a problem if the idea is to make it essentially
non-permanent...it'll be difficult to attach it and support it w/o a
solid tie-in to the floor. And a solid tie will be hard to achieve w/o
damaging the floor at least in a couple of spots.
