I think your problem is here:
<Directory "c:/wamp/www/">
Options Indexes FollowSymLinks
AllowOverride all
Order allow,deny
Deny from all
Allow from all
</Directory>
Try:
<Directory "c:/wamp/www/">
Options Indexes FollowSymLinks
AllowOverride all
Order deny,allow
Allow from all
</Directory>
You can read about ordering here: http://docstore.mik.ua/orelly/linux/apache/ch05_06.htm
From what I can tell, you are essentially saying: process all allow directives first, then any deny directives. Then you have Allow from All, which is then counteracted by Deny from All. Switching the ordering to deny,allow should fix it, or just removing the Deny from All directive. I did not test though.
