If you want to see, and edit files on Win-7 from Fedora, you need a samba client on Fedora. Konqueror is a SMB client that is installed on most KDE desktops. Nautlis is installed on most Gnome desktops. Either will connect to a windows shared directory. I don't use Gnome, so you may have to look around to find out how, if you are using Gnome. In Konqueror, in the address bar, you type 'smb://hostname/sharename' ( without the quotes ). Of course you need the real names you defined.
You can also browse the network, by workgroup name. You can try smb://workgroupname ( use the real work group name ). You should get a listing of the systems belonging to that work group.
If you want the sharing to go the other way, you will need to install Samba server in linux, and configure it. Install it using the package manager that comes with Fedora. To configure it, you will need to do some reading. Here is a very good reference. http://us1.samba.org/samba/docs/using_samba/toc.html
If you want a tutorial on how to get a samba server running, they are on this board, here -->http://www.linuxquestions.org/linux/answers/Networking
As for the Win-7 system, you need to configure workgroup and a hostname as you would on any windoze machine. If you look in the Samba reference I gave you above, ch-3 deals with various flavours of windoze. Win-7 needs the same conifg as any other windoze version.
