How to add a tweet checkbox to form submission


I’m new to all this and frankly don’t have the time right now to learn the T-API. I have an old client that wants to add a Tweet checkbox to his forum sites so that his users can check it and have it automatically tweet the new forum subject and a link to the new topic. I’ve seen some Javascript code that allow you to show something like a tweet form to a user, but we don’t want to add an extra step for the users.

This being the case (we want PHP to tweet, not JS), do we need to create a Twitter App or is there a more simple solution?
