I think you should use entity type instead which has a query_builder option.

This link:

http://symfony.com/doc/current/reference/forms/types/entity.html

Describes how to do it.

If, for some reason you really don't want to use entity type, you could always retrieve data within controller and pass it via FormType constructor, which is a little bit quick 'n' dirty but should work just fine...

Controller:

$this->createForm(new MyFormType($results_from_qb), $form_data );

FormType:

public function __construct($results_from_qb){
    $this->results_from_qb = $results_from_qb; // store it into class member field to be used latter in buildForm method
}
