Easiest Way to make a GUI to show the amount of money earned by the player?

I recently tried my hands on coding a simulator game in roblox.

I am thinking of making a GUI so the player no need to look though the player tab list to see how much they have earned.

What might be the fast way to do this? SideNote, The current code I have has the Strength Value directly impacted on the Height of the player. Is there any way so that the player's height would remain after purchasing an upgrade?

Points Script are as below:

local DataStore = game:GetService("DataStoreService")
local PointsData = DataStore:GetOrderedDataStore("Points")

game.Players.PlayerAdded:Connect(function(plr)
    local points = PointsData:GetAsync(plr.UserId)
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    local pointsValue = Instance.new("IntValue", leaderstats)
    pointsValue.Value = points
    leaderstats.Parent = plr
    pointsValue.Name = "Strength"
end)

game.Players.PlayerRemoving:Connect(function(plr)
    local strength = plr.leaderstats.Strength.Value
    PointsData:SetAsync(plr.UserId,strength)
    print("Saved data")
end)

game.ReplicatedStorage.BuyItem.OnServerEvent:Connect(function(plr,weight)
    if plr.leaderstats.Strength.Value >= weight.Price.Value then
        plr.leaderstats.Strength.Value = plr.leaderstats.Strength.Value - weight.Price.Value
        local newWeight = weight:Clone()
        local oldWeight = plr.Backpack:FindFirstChildOfClass("Tool") or plr.Character:FindFirstChildOfClass("Tool")
        oldWeight:Destroy()
        newWeight.Parent = plr.Backpack
    end
end)

Thank you!
