[CentOS] Mapping to Samba

Using GUI methods (read: easy for most users), is there a way to map to a Samba share and have it accessible to all applications? Going through Nautilus I'm able to create a link to the shares, but they're not accessible from many applications. And, obviously, this is going to be something that changes per user (different mappings, different credentials, etc), so I can't use a static mapping on the machines. I could live with /etc/fstab entries if they could be dynamically adjusted based on the user that's logging into the system.

How do other people handle this situation?

Thanks, Scott
