I want to use a form to represent a task.   The task is a welcome call.  So
the form will have an order reference number, task id, client information,
product ordered, and phone number (all taken from a database).   The form
should be created with this data present, then sent to a "vendor" who will
make the call.   Thus, the form should have all of the information necessary
to complete the task.

The vendor will make the call to the client, update a field (comments) and
click submit.   The submit function would send XML to an HTTP interface of
some kind and respond with an id number.    That id number will be updated on
the form as a "receipt" that the vendor completed the task satisfactorily.  

My question is, how do I go about creating the form with the pre-populated
data?  Is there an example someplace I can start with?

Thanks - I've read through a great deal of documentation but couldn't find
an example that seemed applicable.
