It actually really is very easy to set up Wordpress Mu on HostGator Shared Hosting (I have Baby Croc).

I believe all HostGator accounts come with CPanel X3 by default.

So, the steps are:

1. Download Wordpress Mu
2. Upload to public html domain you wish to use
3. Create Mysql database and user w/ full rights
4. Run the installer script by going to the homepage with your browser
5. Setup wildcard domains -- this is the one that had me stumped.

To set up the wildcard domains, select "Subdomains" from Cpanel -- not "Add on domains". For your site, put an an * in the form field and then select the shared website from the drop down box. In the other text field, point it to public_html/domain (or whatever folder you have your wordpress files in). It does take a minute or two to take effect in my experience, so I thought I'd messed it up at first, but it really does work!

That's all there is to it.
