The createBlock($class_string) method creates an instance of a block, much in the same way that Mage::getModel($class_string) and Mage::helper($class_string) create instances of models and helpers, respectively.

To create a simple form, you'll need to associate your block with a template, which you can do by calling the ->setTemplate($template_file) method on your newly created block. Other than that, we're going to need more information to help.
