Bash script won't run because hardware won't produce display

Can anyone offer any advice on how to modify the script below to work on a new system we have, that has no graphics capability? We admin the system through a serial RAS device. I've tried running the below script through the RAS and through an ssh -X session. It failed with something like "GTK unable to produce display". Python scripts however do produce menus and such on screen and I don't understand the difference. Any help/advice is greatly appreciated. Thank you.

This script is supposed to produce a text box on screen, that our installers enter a 4 digit code on. That code is checked for validity and if it is, the script completes. I have several other scripts just like this one, all with the same problem. Is is zenity????

Code:
#!/bin/bash

VER=`zenity --entry --text "Please enter the ACG pgm number:" --title "Version Entry"`

if [ -z "$VER" ]; then
	echo "ERROR: Version entry was not provided."
	exit 1
fi

IS_OK=`echo $VER | egrep "[0-9]{4}"`

if [ -z "$IS_OK" ]; then
	zenity --question --text "'$VER' does not appear to be a
valid version string.

Continue anyway?"
	if [ $? -ne 0 ]; then
		echo "ERROR: Invalid version entry."
		exit 1
	fi
fi

echo $VER > /etc/acg-oe-pgm

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME
Test::Script - Basic cross-platform tests for scripts DESCRIPTION
The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or bin as is also commonly used) paths of your Perl distribution. Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible. That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is considered unacceptable. In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking that your module won't on some platform because of the dependency. Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform safety. FUNCTIONS
script_compiles script_compiles( 'script/foo.pl', 'Main script compiles' ); The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. script_runs script_runs( 'script/foo.pl', 'Main script runs' ); The "script_runs" test executes the script with "perl script.pl" and checks that it returns success. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. SUPPORT
