Second basic front end with dialog/Xdialog

The following script reads a string you input and prints it back.

#!/bin/sh
DIALOG=${DIALOG=dialog}
tempfile=`tempfile 2>/dev/null` || tempfile=/tmp/test$$
trap "rm -f $tempfile" 0 1 2 5 15

$DIALOG --title "My input box" --clear \
--inputbox "Hi, this is a sample input box\n
Try entering your name below:" 16 51 2> $tempfile

retval=$?

case $retval in
0)
echo "Input string is `cat $tempfile`";;
1)
echo "Cancel pressed.";;
255)
if test -s $tempfile ; then
cat $tempfile
else
echo "ESC pressed."
fi
;;
esac

Try running the program under console and under X ( after changing dialog to Xdialog as above)
