Create Menu to run Postman API queries

I have some queries in Postman that I want to run from an external exe file. No idea how to accomplish this. There is basic authentication within Postman for the queries. I just want a menu that has 4 items on it. Sales History/Service History/Sales Closed/Service Closed. when you click on it, it starts the API. Obviously need code to manipulate if I need to add more buttons plus the regular error coding if something doesn't work and a cancel/back/exit button.

I really don't know what else you need to know but my funds are limited on this one. I'm pretty good at manipulating programming but I don't know how to create something to access these from Postman.
