team addon?

could someone send me a like to or make a simple addon. All i need is something like in a gamemode people can press F2 or something and make a team, all details are below for this.

  1. people can make teams, private or public so anyone can join or you need a password to join.
  2. people can delete the teams
  3. players on your team will be tagged with like their name in green so you can find them

can anyone make something like this?
