Delphi Gumtree and Craigslist Auto Post

Hi I need a desktop application which can post adverts to [login to view URL] and craigslist.com. The application must be written in Delphi 5/6 or 7. There is no requirement to handle to emails generated by Gumtree or Craigslist, it solely the posting aspect I'm interested in. The data for the posts should come from edit boxes on a simple form. And a course a button for 'Post to craigslist' and a button for 'Post to Gumtree'. Each posting function should return a TRUE if the post was accepted and the HTML from the error page if not. Thanks.
