How do i add like a setting gui?

I tried to watch every YouTube video on how to make one but since they won't work and I checked the scripts.

What I Would Do Was Make a Part Name It Whatever Use It As A variable And Then Use MoveTo() To Get To A Place

Part = game.Workspace.TeleportPart
script.Parent.MouseButton1Click:Connect(function()
	game.Workspace:WaitForChild(script.Parent.Parent.Parent.Parent.Name):MoveTo(Part.Position)
end)

Although Thats Just Some Simple Code But If You Use It It Has To Be A Local Script
