you can use PIL to create the individual frames, but PIL doesn't contain 
any ready-made API for creating stacks; the simplest approach is 
probably to write the frames to disk, and then use the external "tiffcp"
command to build the final file.

outline:

     command = ["tiffcp"]
     # add options here, if any (e.g. for compression)

     for i in range(...):
         im = Image.new(...)
         ...
         framefile = "frame%d.tif" % i
         im.save(framefile)
         command.append(framefile)

     command.append("stack.tif")
     subprocess.call(command)

     # remove frame files here
