quoting and answering your questions:
> "...I want it's localhost to be available from other computers"
Sorry, but "localhost" (meaning "this computer") is the standard hostname given to the address of the loopback network
interface. The name is also a reserved domain name, so you can't make computer's localhost to be avalible from other
computers.

and folders, edit it, test it, view it in browser"
To start with, you need some kind of FTP server software, to provide access/edit files capability for your team.
I think FileZilla should fit your needs.
Second, ensure other computer in your network can "see" the machine WAMP running on. Go "Start" -> "Run", type "cmd" there
and press enter. In text console appeared type:
C:\Documents and Settings>ipconfig
Windows IP Configuration
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . : mydomain.com
IP Address. . . . . . . . . . . . : 192.168.221.235
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.221.1
This is your WAMP machine IP address. try to ping it from another box in your network(e.g. "Start" -> "Run", type "cmd",
In text console appeared type: ping xxx.xxx.xxx.xxx
, where xxx.xxx.xxx.xxx - IP address in your case.). If it pings as
well you can proceed with next steps, if not - check your network/firewall settings configured as well.
The next one, Apache server configuration. Ensure Apache is configured to bind/listen to your xxx.xxx.xxx.xxx network
interface(if it configured to "localhost" it is reachable only for machihe it is running on).
Try run telnet xxx.xxx.xxx.xxx 80
on WAMP machine, if you can see answer from Apache web server than it configuration
is correct. Try the same from another PC in your network - you should get the same response from Apache.
If you can ping and connect by telnet to your WAMP machine from another, then try access it in browser by typing
http://xxx.xxx.xxx.xxx/
After this you can proceed with FTP server configuring and share your work. You can either use classic windows
file sharing.
In your case(developers team) recommended to use Subversion for code versioning.
