Internal wall

My shed is called the play-room and houses exercise equip, tools (non-gardening type), general storage, and importantly homebrewing supplies and related work-space. Generally, I do my woodwork outside under the carport but this is becomming uncomfortable.
My intent is to build a wall to dust-proof the brewing from other activities and can get a three-panel, coloured toughened glass window assembly about 7x10 feet (including the wood frame) for $80. The play-room is 13' wide with 8'6" ceilings.
So the question is:
1. Do I pre-fab the wall on the concrete floor, using the window as a template, and lift it (which I think is easiest for me); or
2. Do I frame the wall in the traditional erect manner, hoping to fit the window properly?

If No 1 is the way I proceed I'm concerned about rigidity during lifting - not only is the window cavity a major 'hole' but a standard door space has to be left too.
I can capably work on the floor, but lifting and climbing are, er, hazardous.

Soth,
build the wall on the floor and then stand it. Run the bottom plate right though the doorway and cut it with a handsaw once the wall is up and fixed. A shallow cut at either end of the opening on the underside of the plate will save your handsaw from hitting the floor when you cut through. Frame up the window opening (allowing 5mm horizontal & vertical clearance) nail some temporary braces across the opening to give the wall some stiffness when you stand it. Finally leave out the noggins adjacent to the window and door openings. This will give you a bit of leeway when you fit your jambs to get them plumb.

(ps. if the "traditional" manner is to build the wall in situ, then I've never built a timber stud wall in the "traditional" manner.;)

Thanks Mick. "leave out the noggins adjacent to the window and door openings", I did not think of that.

As far as tradition goes, keep in mind I'm about twice your age. :D
