✅ Generating an exe with c#

Im not sure if this is an advanced or simple question, but I wanna make a file that can generate an exe through a gui. I'm thinking of making a Remote Access Tool for fun as a project (not for skid or unethical reasons), and I kind of understand the actual code itself but how to I make a file that can generate an exe because I dont wanna hardcode stuff like webhooks, ips, etc
