In many wordpress themes we want to create the wordpress widget. For creating the wordpress widget you just need to put following code in functions.php file.
This functions.php file you can find in wordpress theme folder.

class My_Widget extends WP_Widget {
function My_Widget() {
parent::WP_Widget(false, 'Our Test Widget');
}
function form($instance) {
// outputs the options form on admin
}
function update($new_instance, $old_instance) {
// processes widget options to be saved
return $new_instance;
}
function widget($args, $instance) {
// outputs the content of the widget
}
}
register_widget('My_Widget');

this code

<?php
class bm_widget_popularPosts extends WP_Widget {

function bm_widget_popularPosts() {
parent::WP_Widget(false, 'Popular Posts');
}

function widget($args, $instance) {
$args['title'] = $instance['title'];
bm_popularPosts($args);
}

function update($new_instance, $old_instance) {
return $new_instance;
}

function form($instance) {
$title = esc_attr($instance['title']);
?>
<p><label for="<?php echo $this->get_field_id('title'); ?>"><?php _e('Title:'); ?> <input id="<?php echo $this->get_field_id('title'); ?>" name="<?php echo $this->get_field_name('title'); ?>" type="text" value="<?php echo $title; ?>" /></label></p>
<?php
}
}
function bm_popularPosts($args = array(), $displayComments = TRUE, $interval = '') {

global $wpdb;

$postCount = 5;

$request = 'SELECT *
FROM ' . $wpdb->posts . '
WHERE ';

if ($interval != '') {
$request .= 'post_date>DATE_SUB(NOW(), ' . $interval . ') ';
}

$request .= 'post_status="publish"
AND comment_count > 0
ORDER BY comment_count DESC LIMIT 0, ' . $postCount;

$posts = $wpdb->get_results($request);

if (count($posts) >= 1) {

if (!isset($args['title']) {
$args['title'] = 'Popular Posts';
}

foreach ($posts as $post) {
wp_cache_add($post->ID, $post, 'posts');
$popularPosts[] = array(
'title' => stripslashes($post->post_title),
'url' => get_permalink($post->ID),
'comment_count' => $post->comment_count,
);
}

echo $args['before_widget'] . $args['before_title'] . $args['title'] . $args['after_title'];
?>

<ol>
<?php
foreach ($popularPosts as $post) {
?>
<li>
<a href="<?php echo $post['url'];?>"><?php echo $post['title']; ?></a>
<?php
if ($displayComments) {
?>
(<?php echo $post['comment_count'] . ' ' . __('comments', BM_THEMENAME); ?>)
<?php
}
?>
</li>
<?php
}
?>
</ol>

<?php
echo $args['after_widget'];
}
}
?>
