Have a look at PAR and it's associated scripts. Although you will have to write a script to ask the questions and act accordingly, you can do something similar to what I have done previously. I used pp to create an executable. The script inside the executable asks the basic installation instructions and expands a second zip file (could easily be a tar.gz file) to where it needs to go.

If you do have to roll-your-own then PAR does a lot of the hardwork for you. For the question and answer bit look into Term::ReadLine
