How to refresh a graphical display through bash script

Hi friends ,

Firstly I am not sure if this is the right place to ask this question.
My problem is -->

I need to display a message graphically using a messagebox or textbox through bash script. However the message should be keep changing every 4 secs . I input the message from a file and use "gxmessage" to display it .

Code:

gxmessage -nofocus -center -title "Welcome screen" -geometry "600,600" -wrap -file $random

Where "$random" is some random data from a file.
But the problem is , how should I refresh the same gxmessage message box,putting different message each time .

I thought of

Code:

while :
do
        sleep 4
        if ps | grep "gxmessage"
        then
                killall -9 "gxmessage"
        fi
        gxmessage -nofocus -center -title "Welcome screen" -geometry "600,600" -wrap -file $random &
 done &

I do not like this solution and it looks ugly too , because it is visible that the message box is getting killed and forked every time .

Can't I use the same gxmessage message box for all the messages just by putting new messages and hence refreshing the same box.
Any idea , anything other than gxmessage will do , if a solution is somewhere else.

Thanks.
D.
