It's not CCK, but try Web Links (http://drupal.org/project/weblinks) or Site Notes (http://drupal.org/sitenotes). Web Links does notify CCK about the extra fields so they can be reordered.

Subject: [development] How to create a content type and a field

Please, can you give me a example(or a module that does this) how to create a content type inside a module and how to add a new field to the content?

Thanks
