How can I add a queue by using GUIs and frames?

I need help on adding queue for my game... What I am thinking of is the player must press a button saying "Play" to start searching for a game... once 10 different players will press that button they will connect and they will be teleported into a lobby which will exist for 2 minutes, on those 2 minutes people that have pressed the button will be added into that lobby... when 1:30 minutes have passed there will be a text saying "30 seconds until the game starts" and then the people that are in the lobby will get teleported to the map. Could someone explain me with steps because I am an amateur on ROBLOX Game Developing.
