There are many ways to add desktop icons to computers and users in particular organizational units. First, are you adding icons like My Computer and Internet Explorer? If so, those are registry tweaks. Otherwise, you're just adding regular files.
In any case, you can use any method available for deploying registry settings and files to desktops through Active Directory. Possibly the cleanest method is going to be building a Windows Installer package file that installs those desktop icons, and then deploying the package file through a group policy.
You can also add the desktop icons using login scripts that you configure for each organizational unit.
