Just a simple Sharepoint Client object in a aspx page or HTML page

Hi I am learning the above and would like a simple HTML/ASP.NET page which will use the SharePoint object model . I know you can put into a Content Editor webpart but i want to achieve this on a HTML page or asp.net page say sitting on the publishing template or _layouts page or a module.

If you have the complete page thats great .


Cheers
