Anybody know a basic GUI script I can use?

I can't find an updated GUI that kicks players from the game, not ban, kick, I also don't know if there is a script that can mass kick a server for example there is a chest in the middle of ana arena and you have sweaty tryhards, how do I kick everybody from the server so I am the last human remaining?  Also, is there a teleporting GUI?  I am looking for something that teleports people to you, you to people, and whole server to you.
