The programs that are running from cron don't have a tty associated with the process so there is no "screen" for your script to pop up a message in.
If you don't tell a script where to send output (the > /dev/null in typical lines), output is generally e-mailed to the account that owns the crontab. If you don't add the last bit (2>&1) to the command, anything sent to STDERR will be e-mailed.
Generally, as an admin, I'm either redirecting my crontab output to a log file (for errors) or to a specific output file. For example:
This will create a webpage that webscan generates and e-mail any errors (STDERR output) to me.
So you really can't have a popup window created from a crontab.
Just write the info to a log file and e-mail it to yourself or to a group if more than one needs to see it.
Oh, and what's the "say" command? The only reference I can find to it is the OS X say command which converts text to audio output. Just curious.

bbrun
bbrun(1) bbtools bbrun(1)NAME
bbrun - An elegant tool for the Blackbox window manager that runs commands
SYNTAX
bbrun [OPTIONS] [-- [-display <display>]]...
DESCRIPTION
bbrun is a small but very useful application. It makes it convenient to quickly execute commands from the blackbox or fluxbox window man-
agers. bbrun is very similar to KDE's Alt+F2 Run Command dialog box. When launched, it occupies a small portion of the desktop and docks
itself to the right side of the screen. The run dialog is opened by clicking on the tiny bbrun window.
You don't necessarily need blackbox for this program to work. It looks just as good in fluxbox, but it won't look the same in other window
managers.
FILES
~/.bbrun_history
OPTIONS -a, --advanced - advanced mode, shows more options than the normal command entry box. The default is for it to be in normal (tradi-
tional/simple) mode.
-h, --help - this help screen
-i, --history-file=<history file> - set the history file to use. (default:
~/.bbrun_history)
-v, --version - print the version number
-w, --withdraw - withdrawn mode, will go straight to command entry box
Options that must occur after '--' if they are used:
-display <display> - set the display that the gearbox should show up on
GENERAL USAGE INFO
bbrun can be run in normal mode where it creates an icon that sits in the slit. You can then click on the gear icon to make the text entry
window popup. You can also run bbrun in withdrawn mode by specifying the -w flag. This is ideal for use with the key shortcut program
bbkeys since it will jump straight to the text entry screen. bbrun also supports the 'escape' and 'enter' keys for those of you who like
to use the mouse as little as possbile.
bbrun keeps a history of your most recent commands. The history list is stored in the '.bbrun_history' file in your home directory. If the
file does not exist it is created automatically.
Also keep in mind that you need quotes when you specify arguments with spaces in them. eg. mpg123 '/mp3/Creed - Higher.mp3'
