I think that you can.
Download the phpMyAdmin.
Put it in <wamp>\apps\phpMyAdmin2.6.4
(<wamp>=your wamp directory, the defualt is C:\wamp)
After you did it click on the system tray icon wamp and click on:
Apache>Alias directories>h ttp://localhost/phpmyadmin/
Its will open for you a text file.
The first line should be written like this:
Alias /phpmyadmin "c:/wamp/apps/phpmyadmin3.2.0.1/"
Change it to:
Alias /phpmyadmin "c:/wamp/apps/phpmyadmin2.6.4/"
Now open [
localhost] and enter to phpmyadmin.
I think that it should be work...

Post if it works\doesn't work...
