If you would like program that can be basic or can suit the advanced webmaster then I would recommend MoreMotion Web Express 3.3 at: http://www.moremotion.com/webexpress/index.html
An added bonus is that this programme is free!
I like this program because it is free, simple and fast to create websites.
I think I can help you quite a bit with web design although I don't think I will be much use if you want to know about servers and scripting languages.
The Best Designs are simple. Try researching the meaning of colours as colours can set the users mood. Choose a colour scheme according to your audience.
Include good photography on your site, don't put distracting clip art that 6 year olds incude in their Word Documents. Try nice icons. I would recommend icons that are like web 2.0 (try searching "web 2.0 icons" on google). Try and Include a shiny feel to your website and the design should be modern and interesting.
I'm sure you can find many photoshop guides that will help you design even if you don't own a copy of photoshop you can still learn from them.
I hope this helps resolve your issue!
