Desktop Software registration module using infusionsoft api

We have a few different softwares that we want to sell that don't have any registration modules built for them. We use infusionsoft to allocate liscense keys, and what we would like to do is have you create a program or utility for us to be able to add in our windows install. This little registraation utility or program will run first before the software does, and use the infusionsoft api to check the email address and license key (inputs needed will be name, email, liscence key) and if valid, stores the data in the same folder and then allows the main program to run.
