Start Launcher is an tiny application that will work on any screen resolution and which lets you assign two programs to the Start Menu button, one for tapping and one for tap and hold.

To get started, download Start Launcher and install it to your device. Launch it from its icon in the Programs menu and the window popping up will allow you to set up two custom applications which will run, one, when you tap the Start Menu and the second, when you tap and hold it; you can also specify arguments to your executable. You also need to specify a screen resolution (QVGA will work for WQVGA and VGA will work for WVGA).
