How do you make a vehicle GUI? URGENT

I am doing a AGT (advanced GUI train) and i need help to make a gui that controls it!

You could use the GetMouse() method, it simply acts like a mouse from tools and hopperbins.

If you need an example;

-- Must be in local script
p = game.Players.LocalPlayer
mouse = p:GetMouse()

mouse.KeyDown:connect(function(key)
	if key=='w' then
		print 'forward'
	end
end)
