Convert Windows XP batch file to AutoIt or equivalent, with some enhancements

I wrote a batch file that opens two programs, asks a "choice" question and runs the appropriate shortcut based on the answer, and then displays a series of png and animated gif images at a specific window position to provide instructions to the user. I'd prefer a Windows GUI for the "choice" question. I also need to add another question and branch for it. I've been using Irfanview to display the images but it cannot control the position of animated gifs. There are some other small refinements that I suspect could easily be handled by Autoit instead of what I'm using (e.g., I use Zmover to position the program windows, and again IT cannot control the position of animated gifs!). Windows XP is the OS this project will need to run on.
