Yes there is a GUI available. It is called Ansible Tower. Although you can get a licence for free (up to 10 machines) this is a paid GUI. the more servers you add to tower, the more you need to pay.
This GUI provides you a couple of cool things. it connects you to an SCM where your Ansible-playbooks live, and it gives you audit trailing for auditability. If companies do not want you to use CLI this is an good alternative, although I prefer the CLI.
