Key Press php-gtk1

First, I am still using php-gtk1. I'd like to make the move to v2 but
do not have the luxury right now.

I am looking to detect when keys are pressed (and held down) in
php-gtk version 1. This is for a "two hand, no tie down" safety
feature on our machines. Access to our machines is made possible by
lifting the top of the machine using air cylinders. The air cylinders
are controlled via an electric valve. To lower the top I need to
require the user to press two keys on opposite sides of the keyboard
and keep them depressed until the top closes completely. If they
release before the top closes completely the top should go back up.

Is there a way I can monitor key press and key release in version 1 of php-gtk?
