|the homepage is typically INDEX.HTM or INDEX.HTML or INDEX.PHP or something like that|
in my limited experience, i find that using a ftp program such as FILEZILLA http://filezilla-project.org/, i can access my web site using the same access information as for CPANEL
if this works for you, then you can download your site to your computer, do the edits and upload the files you have changed
hope this helps
