The ability to have stars that light up is not part of the native campaign builder or web form. However, there is an HTML section you could insert and if you have a code or you could possibly have them design something, but I think it would be pretty difficult.
What we do is when we send them the email to ask for the review is that we send an email with two images. One image is four or five stars and the other image is one through three stars. If they click the 4/5 stars they go to one page and if they click the one through three stars they go to another page. So we do our split from the email not from the web form.
