I think you need to look at Linux socket programming. This page explains how to do this with C++ for a PRG system. It's not an apples-to-apples example, but it's conceptually the same.
The long of the short of it is that I think you need to open a socket to the Linux server and then execute the script, capture the data, parse the data and then let your application take action on it.
