Display Record Summary Inside of the Form

Display Record Summary Inside of the Form

How can I easily display a record summary, record detail inside of a form.

Example:
I have an order form. If the order form is a split order, then I want it to show a previous order (un-editable).  I have the logic of finding the previous order, I just need to display it.

Possible Solutions:
  1. I could create a stateless form and then have the form populated. Thats a lot of work to just show a record.
  2. Use the notes field and fetch the data and populate with HTML. This also is a lot of work since Zoho displays records single records all the time.
Is there a way to do this that is easier than the solutions above? 

Thanks in advance!!
