I don't think crond is really intended to start things that are
interactive.  It is intended to schedule "recurring tasks" that should
occur on some schedule irregardless of someone being logged in, so the
intent is that it not interact with the desktop....

To me it sounds more like you want something to start automatically when
you start your X-based desktop?  If that is the case, you could place
the script you developed into the directory /etc/X11/xinit/xinitrc.d/
and it should run whenever anyone starts their X desktop....

HTH,
