Magento Admin Category tree

Question

How do i show the Category tree which is in the Admin menu in the admin section somewhere on other page [but admin side].

Also I dont want to generate tree using custom js. Just need to use the default functions.

$this->getLayout()->createBlock('adminhtml/catalog_product_edit_tab_categories')->setTemplate('catalog/product/edit/categories.phtml')->toHtml();
