Using Custom Post Types in a widget area

Thanks for publishing such a great content. Just one question please. I have created few custom post types. Now I want to display in various sections of the index page where they will be linked to their respective pages. May I know hw can place these custom post types in various sections of the index page by using widgets?

Curremntly, I can not see method by using which I could display the post types in the section I want.

Any and all hep will be appreciated.
