[Zope] Running external applications

I'm a newbie to Zope. I could not get it to run with my webserver, so am using zserver for the moment. How does one run all ones legacy applications eg. windows executables, perl scripts etc. I've checked the documentation and the FAQ but the only external methods seem to be written in Python.
