convert small portion of php application into jsp web app(or java desktop app)

I have with me a software, that fills in and submits data over a web form. It initially asks for all text values required by the form, and then shows only captcha and multiple choice values on screen. Now user has to fill in captcha/multiple choice values and when he clicks on submit, then the form is submitted. I want you to convert this php code (it requires Curl as well) into Java code usable by a jsp web application. If jsp web app is not possible, then convert it into java desktop application. I also require design documents (High level design and detail level design documents) clearly explaining the logic and code flow of your code. Also I want you to add one more ability to existing code- currently data is submitted to one site at a time, (ie captcha of one site is shown at a time for user to fill in). Please modify the code so that captchas (and multiple choice values) of multiple sites can be simultaneously shown. Now user can fill in all captchas and multiple choice values in one go, and when he clicks on submit all the forms are submitted to respective actions. Simple work for a good java/php coder. The original PHP code is attached with this bid request. Take a look and put in a bid. Regards, Arvind.
