If your page has (except username/password) buttons and checkboxes, then it's a cgi script. Just see which is the URL of the page called (or even better the form "action" as it might redirect you). Then call that URL (or the action script) with the params you want on the Location bar, thus simulating a form GET. Even if it posts the form with a PUT, it should accept the parameters on the url if it's written with CGI.pm (I don't know about others). If that doesn't work, then I' m afraid I cannot help.
