You will basically need to come up with a desired UI layout. For a file
dialog, you could do something similar to this:
import os.path
import maya.cmds as cmds
homeDir = os.path.expanduser("~")
filter = "Jpeg Images (*.jpg)"
filePath = cmds.fileDialog2(cap="Choose File Save Directory",
startingDirectory=homeDir,
fileFilter=filter, fileMode=0)
print filePath[0]
That would get you the desired folder and filename, which you could then
split apart and attach your tile numbering to. For the most part, the
Python versions of the UI elements work the same as their MEL
counterparts. If you can write the UI in MEL, it's pretty easy to
translate it to Python. Python gives some extra benefits in terms of
string manipulation and other things. I haven't played with it, but it
looks to me like this whole project could be written in Python. I left the
uvSnapshot command in MEL for the sake of demonstrating the appropriate use
case of calling MEL code from Python in my earlier code.
If you're struggling with converting from MEL to Python, I did a basic
writeup on my blog outlining some of the major differences.

I unfortunately haven't had time to continue the series beyond the basics
of variables, but it's at least a start.
