MakeDesktopShortcuts is a service menu extension for Dolphin
that allows you to add quickly desktop shortcuts of one or more
folders with a mouse click.
More precisely, it doesn't create any symbolic link
but it generates a .desktop file launcher that points to the selected folder.

To install:
# cd /etc/yum.repos.d/

# wget http://download.opensuse.org/repositories/home:/Faster3ck:/fasterindesign/Fedora_15/home:Faster3ck:fasterindesign.repo

# yum install MakeDesktopShortcuts
