Is there any particular reason you want to do this using cron? It will probably be possible, but it's not straightforward and is certainly not worth the effort. Why not add skype to your startup applications?

Skype was just one example to test the function for starting commands.

In that case it's a very bad example since it is a graphical program and depends on all sorts of other things being loaded for it to run. What is it you're actually trying to achieve here? Do you want to run GUI programs with cron? Do you just want to run GUI programs on reboot? Non-GUI programs on reboot? Please [edit] and explain what your final goal is, I doubt that cron is the right way to do it here.

Just to add, when cron runs tasks, by default, it doesn't let the application show any window, since it doesn't provide the same environment variables you would have in a normal terminal. You could set the environment variable that lets applications display GUI windows, but if you're using it with the @reboot command, you're better off just using startup applications.
