Urgent! Need help with Illustrator. (Icons)

[Albacore]

The way I see it, that there is only 1 shape that has been reflected, duplicate and scale. Draw the outside large rectangle, then the window like inner rectangle, -- Use Pathfinder-Subtract. That gives the window with no fill. You now want to give this window a bit of Perspective (many ways to do this) I would the Warp menu found half way down the Effects menu--use Shell Lower-0 bend, then turn on preview then move the horizontal values positive/negative to have left/right perspective. That's it really but I would now Expand Appearance so that you can scale and reflect shapes. Use the Pathfinder Tool again but this time use Add to combine the smaller window shape to the larger one.
