Is really simple! Here is a small sample where I extend the content type "Document" by adding the field "Office". Not really useful but shows how it's done. SPSite site = new SPSite("http://moss.litwareinc.com");
SPWeb web = site.OpenWeb("/SiteDirectory/t2");
//Create Content Type (extending Document content type)
SPContentType documentContentType = web.AvailableContentTypes["Document"];
SPContentType newContentType = new SPContentType(documentContentType, web.ContentTypes, "Niklas Document");
web.ContentTypes.Add(newContentType);
Console.WriteLine(newContentType.Id.ToString());
//Add FieldLink
SPField fieldOffice = web.AvailableFields["Office"];
SPFieldLink fieldLink = new SPFieldLink(fieldOffice);
newContentType.FieldLinks.Add(fieldLink);
newContentType.Update(false);
