SQL*Plus will use a default BEQUEATH protocol for local connections, which allows it to connect with or without an active internet connection and bypass the tnsnames.ora connection configuration. SQL*Developer is not designed in that fashion and thus needs a remote database to connect to. You'll need to follow the instructons here:
http://support.microsoft.com/kb/839013
to imstall the Microsoft loopback adapter. After that you'll need to include either the default IP address for localhost (127.0.0.1) or the address you've configured for the loopback adapter during installation as a second ADDRESS mation in the tnsnames.ora file as part of the ADDRESS_LIST. Once that's done you should be able to connect to your local database with either SQL*Plus or SQL*Developer.
