Yes, that's possible. You'd first need to create a PostItem in the folder and add to its UserProperties collection to set the field definitions in the folder. (You can then delete that item.)
Then you can use the View.XML property to handle the view columns. MSDN has articles at http://msdn.microsoft.com/library/en-us/dnout2k2/html/ODC_CustomViews.asp and http://msdn.microsoft.com/library/en-us/dnout2k2/html/ODC_XMLViewDef.asp See http://www.outlookcode.com/threads.aspx?forumid=4&messageid=19 for additional sample code.
