WordPress and phpbb

Hello! Please tell me how to make a form of commentary through phpbb 3.1.x forum without integration like in vk https://vk.com/dev/Comments. That is, in the form itself there is the avatar, name and e-mail and comments field. The man wrote a comment to the site, at the same time gets comments on the forum. Displays the last 10 messages. Online user registration is prohibited. Integration Forum and the site for registered users do not need. Maybe there is such a plugin, but I am not found.
