Chatterbot talk with clickable responses

We are a free educational site for learning English as a Second and Foreign language. We have a "chatterbot" [login to view URL] which students use to practice English. Unfortunately, many beginning learners have poor typing skills. I'd like to have a page where the chatterbot Dave is in an iframe (actually we already have this on our community [login to view URL] ) and below will be lists of questions/statements. Students instead of typing can click these links and this will be put into the text box of the chatterbox and entered as "what would normally be typed". The Chatterbot will respond and the student can again hit a question/phrase to continue the conversation. I'm looking for someone who can get this done and help our community. #1 Is it possible? #2 Willing to pay reasonably but also note - we are non commercial and this is educational. You'd be helping out 1,000s with this brillant idea (if it works). Thanks, hope the above is clear enough. David
