QF Controller, frontend form possible?

Hello Maybe someone can point me in the right direction. I'd like to make a form using QFC, a front end to database inserts, updates and deletes. Each process would be a "miniform". After a successful processing the form should return to the initial frontend page. I've mocked up five submit buttons for the frontend page. ............. Home Edit Delete Add This Add That The frontend (home) page would show a buttoned index of selectable items. Only one item from the list could be selected for form processing. By clicking "Edit" or "Delete" the selected item would be processed. Validation as to whether a button was selected would be needed. The form would continue in a "wizard" style and upon success return to the home page. The "Add This" and "Add That" buttons have nothing to do with the index shown on the frontend page. Clicking these buttons jumps to the start of distinctive "wizard" style forms and return to the home page upon success. The home button could be visible at all times which would need no validation to jump to. ............. Is all this possible with one controller? Or do each of the buttons that lead to further processing need their own controller? I've seen references to having multiple controllers but haven't found a sample. With a good addrule on the home page is it possible to require a selected item for the "Edit" and "Delete" buttons and not so for the other buttons? At the end of successful processing I assume I can "jump" back to the frontend page. If someone jumps to the home page in the middle of one of these forms would it be a big headache to save what is in the container to fill the form if they go back to it? Or should I clear the container? Any bits of info would be very much appreciated. Thanks, Roland
