Yes, there is.
The file is called rc.local and usually is found under /etc/rc.d/rc.local (else do a "locate" to find it). Put in all the commands that should be run at startup.
Since this applies to all users, you can not selectively turn it off. If you want this, you could put the commands in the bash profile file (assuming you use bash as the login shell for your users), I always get confused here -- I think it should be in ~/.bashrc or ~/.bash_profile.
Edit: I just noticed that I thought of CLI programs only. I think KDE and Gnome both have autostart options, but I don't know anything about this, since I never used it.
