If you want a form that is detached from the node concept, you just define 
the
form itself and call it from the menu handler directly.  You can use
hook_forms() for it, but don't have to.  The form itself gets submitted as
normal, and you have complete control over it.

A bare skeleton might look like this:

function example_menu($may_cache) {
  $items = array();

  if ($may_cache) {
    $items[] = array(
      'path' => 'example',
      'callback' => 'drupal_get_form',
      'callback arguments' => array('example_form'),
  }

  return $items;
}

function example_form() {
  // define your $form here, reading from the DB as needed.
}

function example_form_validate($form_id, $form_values) {
  // Do stuff with $form_values here and set errors if needed.
}

function example_form_submit($form_id, $form_values) {
  // Do stuff with $form_values here and call DB queries if needed.
}

Now going to /example will display the form defined by example_form(), and
when it's submitted it will first be validated by example_form_values() and,
it passes, will get passed to example_form_submit() for whatever saving you
want to do.

For more information, see:
http://api.drupal.org/api/file/forms_api.html/6
http://api.drupal.org/api/file/forms_api_reference.html/6

You can, of course, get ridiculously more complicated than that (especially
when you start working with custom theming of forms, which is all sorts of
exciting), but that should get you started.

Cheers!
