you've nothing to be ashamed of if that is indeed your first effort, even if you did use a web based program to create the site.
Dreamweaver is superb, but I feel somewhat overrated.
NetObjects is also superb, but in different ways and for different reasons. I feel that it is vastly underrated, mostly by people who don't appreciate its full capabilities.
Now, the tool (or software) you use is not nearly as important as how you use it. I know loads of people who have the latest all-singing-all-dancing software and their results are poor, simply because they have the tools there but don't know how to use them properly.
A close friend (and incredible web developer) stubbornly refuses to go beyond Dreamweaver MX (version 6). She says that she knows it inside out (which she does) and the added features of MX 2004 or the latest version 8 are either of little use to her or she has already written her own extensions to do, broadly speaking, what the latest versions do. She makes me sick... ;o)
Likewise a colleague introduced me to one of their friends who had a two versions old NetObjects program installed from a magazine covermount CD. Their site was, at first glance, stunning. That's the only word I can think of to describe it and it falls well short of the reality. This individual had spent a lot of time learning the program ,reading the NetObjects newsgroups and discussion boards and it all came together for them.
I feel that NetObjects offers a less intimidating learning curve than Dreamweaver, but Dreamweaver has by far a more powerful feature set. Everything in computing is a trade off between features and how easy it is to use.
I'm still waiting for the day when browsers can actually display a page how I intend it to look, where I tell mycomputer what to do and it does it, and where I don't have the headaches currently in mainstream web development...
What I will say is that you should settle on one or the other program and stay with it for several months. Chopping and changing will throw you right off.
Also keep in mind that content is everything - your design should assist and support delivery of the content, but the best design can't make boring or poorly written content work.
Good luck with it no matter which program you shoose to use.
