Yes. PHP/MySQL (what Joomla is coded with) is cross platform independent. It'll run the same regardless of the OS.
All you need to do is to download your site from your host via FTP and place your sites files in WAMPs www folder (C:/wamp/www).
Next you need to backup your database for Joomla, your host should provide a utility for this. If you're not sure ask your host.
Once you have the backup, which normally comes in the form of an .sql file you need to open phpmyadin from WAMP and select the Import tab.
Once your backup is imported you'll need to modify your Joomla configuration and change the MySQL username/password. Default username/password for WAMP is root for the username and no password
