You might want to change your installation of wordpress so that you can re-install manually, or you just want to delete a website and start again. Either way, this is how to delete your wordpress files on Godaddy.
Using a script for the Automatic installation of wordpress can add unwanted files and configuration settings in your version of wordpress. If you have a wordpress site that was installed using a convenient script, you should consider re-installing manually for a clean version, to remove those default settings. You will have to import your existing content from a backup.
Other hosts may have similar methods but the app managers may be in different locations.
GoDaddy's application manager lets you easily install applications like WordPress.

2. Click on "Install and Manage Applications." Click on "Manage my Applications."
3. Scroll down to the WordPress installation (listed by domain name) you want to delete. Click on "View and Manage Details."
4. Click on "Uninstall Application," and then check the box next to "Delete my Database" and "Delete my Files." Type "OK" into the verification box.
5. Click on "Uninstall." Wait a few minutes until WordPress no longer shows up in your application listing.
