just create a cube elongate it. add subdivisions maybe 20 for the height (depending on how much you elongated it)

side view > select faces maybe a few less rows at the top and bottom, uncheck "keep faces together" extrude in a couple of times

bish bash bosh windows!

you get something like this.



i have a question after looking through the thread... how are you going to comp it in PS if you have an animation? will you do frame by frame?
