Well, I'm a bit confused myself (nice to meet you!) .
If you're talking about using Crosswinds.net's "Homepage Utilities"... Yes, you can use FTP software to upload pages to Dream Host, or use your Web browser to do that.
See this link for info:
But using FTP software isn't hard at all. I'd say that if you're coming to DH, you probably want more features than Crosswinds offers (CGI/Perl, PHP, etc.). If that's the case, then you're going to be plenty smart enough to use FTP. But if you have any questions about FTP or HTML, just stop by here and ask!
