gogf/gf ? reverse-engineered prompt

Build me a small GoFrame based web app that runs a local server and shows a simple homepage with a Hello World message. I want it set up in a clean way so I can run it right away with the GoFrame CLI or a normal Go command, and it should feel like a real starter project I can extend later.

Please include a basic route, a simple response, and whatever project structure makes sense for a lightweight Go service. If there are any current setup details I should know, look up the latest docs online and follow the current recommended way. Keep it simple, production friendly, and easy to understand, with clear defaults and a nice starting point for adding more pages or API endpoints later.
