Write some software -- 2

I'm Trinidad, at your service. I've been a professional software developer for more than a decade and have a good deal of experience with both C and C++ on the Windows platform. Could you kindly answer me some questions: 1) To be clear, it's just a program that once you run it, it will install some chrome extension, is that correct? 2) Will the Chrome extension be placed inside the EXE or somewhere else in the hard-drive? Do you want to be able to modify the Chrome extension that is bundled with the EXE? 3) Do you have the Chrome extension already developed or want me to develop it also? Thanks for your time
