[SOLVED] Step by step for creating a page/post template in Atahualpa

I'm not a php guru and want to create page templates. I know that you can copy the index.php and I know the little snippet of code you put at the top but it's all the code that goes on the page I'm not sure about. For instance if I wanted to create a page template that had no sidebars I know I can do that by putting the id of the page I don't want sidebars on but how do I create a template that doesn't call them?

I really would like a simple rudimentary step by step as an example. I could use that to jump start my learning curve. Is there a more WYSIWYG way of creating the page template?
