Frontend Submission?

Hi, Would it be possible for a front end submission? I would like my site visitors to be able to create articles but limited to my instruction. For example, I have a website in the poem niche. I would like the front end to have a small box where the user enters a single subject. By default programmed already into the script would be "Write me a poem about", the user simply enters a subject, ie, "Bananas." Script does the job and user is redirected to a paged with the poem about bananas. Could this be possible? Thank you for a great plugin.
