Ubuntu :: Application Launcher Shortcut To Open Terminal And Execute A Command

I'm having Ubuntu Kramic Koala and i want to create a custom application launcher on the panel so when it is clicked it should open a terminal window and run the following command and then show the output for 5 secs and then closes the terminal... how can i do this?

Code:
cat /proc/sys/vm/laptop_mode && sleep 5

the above command is what i want to be executed at time of running the custom application launcher. if i paste the command in a terminal, it will show the output for 5 secs and then terminates... that's almost what i want. what i exactly want is that, i want it to work like when i click on the shortcut launcher, it should open a terminal and then exectues that command, show the output for 5 sec, pause, and then exits the teriminal.
