Place A Dynamic Query List Into A Form

This may be a pipe dream, but let me dream out loud. Below may be overkill, but here’s my challenge.

1. Is it plausible to place a dynamic query list inside a form, assign input field names to the repeated rows?
2. Then from that list, items in the rows could be selected with a checkbox field.
3. Afterward, the results of the items selected would be inserted to an order’s table by clicking the submit button.
4. Once they are inserted in the orders table, they could then be downloaded to the user’s computer.
