Star rating system in front-end form.

I made a front-end form for users (with author, editor and admin rights) to write posts. I done it with ‘WP User Frontend’ plugin. The form has certain default fields like post title, post, content, categories, tags etc. which all work well.

However, I like the star-rating system included in theme. I wonder, is there a way to put the star-rating in the front-end form, so that users who write posts have the option to add rating directly in the front-end, without the need to log-in to wp-admin?

P.S. WP User Frontend has a ‘custom HTML’ option for field, which should allow pretty much everything? I just don’t know what to put in it.
