Using Fedora, I assume that your booting directly into the GUI. Having applications start when you log-into the GUI all depends on which GUI you are using (KDE, Gnome etc...)
I have only ever used KDE, so hopefully someone else can offer some more advice for the others. You can place anything you want started when you boot KDE into ~/.kde/Autostart
If you could provide more details on how you are logging in, and what you need started at boot, I may be able to provide you with a more detailed response.
