It is really simple to set any variables to all layouts in ZF2 by EventManager, just attach the EVENT_RENDER event such as:

class Module
{
    public function onBootstrap($e)
    {
        $app = $e->getParam('application');
        $app->getEventManager()->attach(MvcEvent::EVENT_RENDER, array($this, 'setFormToView'), 100);
    }

    public function setFormToView($event)
    {
        $form = new MyForm();
        $viewModel = $event->getViewModel();
        $viewModel->setVariables(array(
            'form' => $form,
        ));
    }
}
