I want to know how to make a GUI with text on it. I also want somebody to help me with this!
This is Scripting helpers. It is for scripting. What you requested has nothing to do with scripting. But heres a link to a ROBLOX wiki page explaining GUIs.
The basic idea is to select StarterGui, insert a ScreenGui, insert a TextLabel or whatever GUI component you want into the ScreenGui. If you mean through a script, you call the Instance.new function with the class name of the instance.
local text = Instance.new("TextLabel") text.Parent = script.Parent -- code
