Re-using existing forms from other modules?

Hi Everyone. I am creating a new module. I would like to give my users the ability to add a contact in my module in a Jquery dialog box. Is there an easy way to simply include the New Contact form from the Thirdparties module so that I don’t have to recreate a whole new form?

I want just the form to create the contact. Not all the top menu and left menu.

Thanks
