I have BuddyPress installed with WordPress Single User with the BuddyPress plugin and I didn’t see the Create A Group button either.. so I Turned OFF: Let Users Create and Join Groups and TURNED IT BACK ON.. and the button now shows!

Also.. the place where you see the button is: yourwebsite dot com/groups/

You will need to create a link to that “Groups” page as it doesn’t appear in the Admin Bar normally.
