Your code is trying to launch a window for display on your desktop. You cannot really do that from a web application.
Even if the server was on the same machine, you would need to configure Apache environment to know about the X Windows display to use, which will be a non trivial thing to do. Are you really wanting to have your web page launch a graphics window?
