Of course you can create your webquest with PowerPoint® or Mediator®, but the hyper text markup language is more special. And that's not only because it can be used by every Browser!
A webquest in HTML can also be uploaded on a server or an other webspace with FTP-access and other people all over the world can enjoy your webquest very comfortable.

FrontPage® is the easiest way to make a webquest in HTML.
BUT Frontpage is only a generator with creates a calamitous sourcecode which doesn't work with some browsers.
Writing your own sourcecode is harder, but it's great many more professional!

Here are the important steps to create a webquest in HTML:

1. Templates

At first you need a template. Professionals make their own sourcecode, but that's maybe a work of many days!
It's simpler to download a template from an other website. The internet is full of free ones.

One german site: http://www.webmaster-elite.de/index.php?page=webtemplates&sort=free
One english site: http://www.freewebtemplates.com/

2. HTML - the language

You can't learn HTML in one day! If you want to learn this language, it will take a long time. The most important things are learned in some hours, but a professional webdesigner will never stop learning. HTML is an expandable language. Stylesheets, PHP and other languages for HTML have been invented until now.

Most HTML Tags, their meanings and the HTML basics are available at Selfthml.org

3. Programs

Phase5, maybe the best free HTML -Editor (german version):

If you still want to make an webquest in HTML, you need an HTML program.
You can work with HTML by using your texteditor, but that's not really the best way. ;-)
The best program is Marcomedia Dreamwaver®, but unfortunately it costs 600 € !!!
My personal favorite is "phase5".
Some other open source projects like NVU are also interesting, but the current version of NVU destroys your structure every time you're loading a file. :-(((
