Creating forms are easy with Dreamweaver, however without any programming knowledge they are useless. Be sure to learn a server side language such as PHP, ColdFusion, ASP or any other language that can process info from your forms to a server.
Here is a great site to teach yourself these languages: http://www.w3schools.com/
In this tutorial we will be creating a contact form. Fields that we will include are:
Step 1: From the top menu, go to Insert -> Form -> Text Field. A window will then pop up asking you to fill out some info.
Type a name for the ID and also a Label. I usually just type in the same name for both.

Step 2: If your properties panel isn't open go to Windows -> Properties. Then click on the text field you just inserted. In the properties panel there a few options you can set.
Init Val - this sets the value of your text field, the name you give it will show up in the field.
Char Width - type in a number to set the width. 25 - 40 is a good range to stay within.
Note: this number is not in pixels, so if you type in 100px you will get a huge width.
Max chars - Set the number of characters you want someone to type.
Step 3: Continue to add the rest of your text fields. On our last text field "Message" in the properties panel choose Multi line. This is so people can write a little message or description along with their information before sending.
Another way of doing this is to choose Insert -> Textarea instead of Text Field.
Step 4: Adding a Submit and Reset button. Go to Insert -> Form -> Button. The same panel that showed up for Text Field will appear.
By default the button will say Submit, but you can change the value and action in the properties panel.
