Open submitted form data in thickbox

Hi to all! I’m working on my plugin and I need help.
In backend, after a form is submitted I’d like that the result page opens in a thickbox, so leaving the parent page with form in background. Note that the result page starts using headers to send newsletter with mail(), then it must show result. I’m using wp_enqueue_script to load jquery and thickbox. Any idea for the code for the form and for the submit button to load thickbox? I tried a lot of snippets but with no luck.
