Requesting some STEP BY STEP Guide about: how i should write a script?

Im making a ”Simon says” type game, is just that i dont want the ”hints” to be on the screen,but i want them to be on a part which has a SurfaceGUI which has a TextLabel in it. now im using that script:

the question is: what i should EXACTLY do , to ”move” the Instance.new('Hint') on that part as a text?

   blue = script.Parent.B
   yellow = script.Parent.Y
   red = script.Parent.R
   green = script.Parent.G

    while true do
hint = Instance.new('Hint')
hint.Parent = workspace
hint.Text = 'Get Ready'
wait(4)
hint.Text = 'RED'
wait(6)
blue.Transparency = 1
blue.CanCollide = false

yellow.Transparency = 1
yellow.CanCollide = false

green.Transparency = 1
green.CanCollide = false
wait(10)
blue.Transparency = 0
blue.CanCollide = true

yellow.Transparency = 0
yellow.CanCollide = true

green.Transparency = 0
green.CanCollide = true

hint.Text = 'BLUE'
wait(6)
red.Transparency = 1
red.CanCollide = false

yellow.Transparency = 1
yellow.CanCollide = false

green.Transparency = 1
green.CanCollide = false
wait(10)    
yellow.Transparency = 0
yellow.CanCollide = true

red.Transparency = 0
red.CanCollide = true

green.Transparency = 0
green.CanCollide = true

hint.Text = 'GREEN'
wait(6)

red.Transparency = 1
red.CanCollide = false

blue.Transparency = 1
blue.CanCollide = false

yellow.Transparency = 1
yellow.CanCollide = false

wait(10)
red.Transparency = 0
red.CanCollide = true

blue.Transparency = 0
blue.CanCollide = true

yellow.Transparency = 0
yellow.CanCollide = true

hint.Text = 'YELLOW'
wait(6)

red.Transparency = 1
red.CanCollide = false

blue.Transparency = 1
blue.CanCollide = false

green.Transparency = 1
green.CanCollide = false

wait(10)
red.Transparency = 0
red.CanCollide = true

blue.Transparency = 0
blue.CanCollide = true

green.Transparency = 0
green.CanCollide = true

end
