Make a billboard gui and parent it to the humanoidrootpart and make the main button used to show all the buttons, something like this:

local Gui = --Gui

game.Players.PlayerAdded:Connect(function(plr)
local Character = plr.Character or plr.CharacterAdded:Wait()

Gui:Clone().Parent = Character:WaitForChild("HumanoidRootPart")
end)

And just program the logic for the buttons inside the billboard gui locally.
