I think he meant to open up a program from a CLI such that it appears in 
his GUI.

To do that, set the $DISPLAY variable to your GUI's display, then run 
the command.

For instance, I'm running X at :0

If I open a new virtual terminal (CTRL+ALT+F2) and type the following:
DISPLAY=:0 xmms

then go back to the GUI (CTRL+F7), I can see that the XMMS has opened 
there. You should be able to do this from cron as well
