I was wondering if it is possible to create a log in button with people using there twitch credentials to log in, to build a database for players to join a que to play wither her & to see if they are subbed to the channel or not to allow them to join.

Yes

Authentication is covered here Authentication | Twitch Developers it uses oAuth
