There are two steps:

function my_plugin_rewrite_rule() {
  global $wp;

  $wp->add_query_var( 'show_hello_world' );
  add_rewrite_rule( 'show-hello-world/?$', 'index.php?show_hello_world=1', 'top' );
add_action( 'init', 'my_plugin_rewrite_rule' );

That takes care of rewriting. Remember to flush the rewrite rules.

Now, your plugin can check for get_query_var( 'show_hello_world' ); and load a certain file:

function my_plugin_template( $path ) {
 if ( get_query_var( 'show_hello_world' ) )
    return locate_template( 'my-plugin.php' );
    return $path;
add_filter( 'template_include', 'my_plugin_template' );
  • A little more laconic way to create query var is add_rewrite_endpoint( 'show_hello_world', EP_ROOT ) (but the check would have to be slightly different since it won't be 1, but just "set" in query vars without anything else in URL after).

In your header.php, page.php, or index.php, add:

if (is_page('show-hello-world')) { 
   echo "Hello, world!";
