I don't think there is a way to do this with HTML. If there is a way it would probably be very complicated and probably involve ajax/php and either a database or an xml file. If you wanted to make it somewhere close to instant you could set up your second page to check a database or XML file every couple seconds using AJAX and the have your first page update your database or XML file when the user clicks on the button. It would be semi complicated but you could do it.Best of luck.

If the first page opened the second (i.e. with JavaScript), and they are on the same domain, then you can interact with it directly. Otherwise you will need to go via the server, as migroo says.
