How can I make a GUI that awards you daily cash?

Basically, I want to know how I can make a GUI that gives you the leaderstat "Cash" each day and increases as the player gets on the game each day, I want it so when a player clicks the "Claim" button it doesn't come back when the player resets and makes the player be able to claim the next login award on the next day, if they don't come the next day but come after the day they hadn't came on, it resets the timer.
