You have the my_plugin_register_widgets function inside the My_Plugin_Widget class. It belongs outside of the class, and you also had the class name as WP_Widget when it should say My_Plugin_Widget. Then you need the add_action function after that to enable the widget. I provided the full solution in case you run into any other issues.

plugin.php 
<?php

// Widget class
class My_Plugin_Widget extends WP_Widget {

    // Instantiate the parent object
    function my_plugin_widget() {
        parent::__construct(false, 'My Plugin Widget');
    }

    // Widget output
    function widget($args, $instance) {
        extract($args);
        $title = apply_filters('widget_title', $instance['title']);
    }

    // Save widget options
    function update($new_instance, $old_instance) {
        $instance = $old_instance;
        $instance['title'] = strip_tags($new_instance['title']);
        return $instance;
    }

    // Output admin widget options form
    function form($instance) {
        $title = esc_attr($instance['title']);
        require('inc/widget-fields.php');
    }

}

// Register the widget
function my_plugin_register_widgets() {
    register_widget('My_Plugin_Widget');
}

// Enable the widget
add_action('widgets_init', 'my_plugin_register_widgets');
