Delphi

kylix

This is a brand-new (Feb.2001) commercial offering from Borland (aka Inprise). In short, it is a Linux port of the famous object-oriented Pascal ("Delphi"). kylix is unlikely to be on your Linux distribution CD, you must pay for it, but if you want the best rapid application development (RAD) platform with a code portability between Linux, MS Windows and the Web, large number of pre-built components, etc., kylix is likely the best. In my opinion, Delphi is significantly better than MS Visual Basic.
