You can create widget like that:

class FormWidget extends Widget
{
    /**
     * @return string
     */
    public function run()
    {
        $model = ...;// code to create model

        return $this->render('_form', [
            'model' => $model
        ]);
    }
}

And in layout input widget like that:

<?= FormWidget::widget() ?>
