Creating a DW form without a datasource

I would like to create a complex form in the datawindow painter prior to having the database tables created. Is it possible to create the blank form and than add the data after the fact?  Also, I would need the form to stay intact after adding in the SQL and or stored procedure that will obtain the data from the database. Attached is a sample of what this form will look like.

Any ideas would be appreciated.

Thanks
