I have a fully functionnal php-gtk application doing that task :
 - check for updates in background,
 - if update is available, notify user with a message in statusbar,
 - then user only has to click Update button.

- this software is locate here : http://php.classes.free.fr/php/gtk/EasyTunes/
- there is a screenshot but not some showing updates.

the interesting part is method lib/FreeTunesGui.php

        # just after update, reload a new process (just like shell
exec) ; current process give up, a new one is created
        protected function reload(){
                $this->main_quit();
                $cmd = DIR . '/easy-tunes';
                $args = array();
                pcntl_exec($cmd ,$args, $_ENV);
        }

here, we restart a new process (with GUI) ; this is the shell
equivalent of : exec $cmd

for your information, update checking is done with lib/Update.php
class. We just need to compare
a file containing local version against latest version available on
remote site. Software version is
handled in a pure text file.
