Custom field to widget

Hello folks!

I have a custom field type that i use for my testimonials page, and it goes like this:

/* Testimonial */
function my_post_type_testi() {
	register_post_type( 'testi',
		array(
				'label'             => theme_locals("testimonial"),
				'public'            => true,
				'show_ui'           => true,
				'show_in_nav_menus' => false,
				'menu_position'     => 5,
				'rewrite'           => array(
					'slug'       => 'testimonials',
					'with_front' => FALSE,
				),
				'supports' => array(
						'title',
						'custom-fields',
						'thumbnail',
						'editor')
					)
				);
}

I was wondering how can i show entries from this page in widget on my site sidebar?

Any help would be appreciated 🙂
