Based on that comment, you want to hook a function to your plugin's activation hook, which inserts a WordPress post object into the database;

function my_plugin_activate()
{
    wp_insert_post(array(
        'post_type' => 'page',
        'post_title' => 'Page Title',
        'post_content' => 'Page Content',
        'post_name' => 'page-slug',
    ));
}
register_activation_hook(__FILE__, 'my_plugin_activate');
