I use Delphi on Windows and have been following the newsgroups from the Delphi developers (Embarcadero) promising a cross-platform Delphi in 2010. They already ship Prism, which uses Mono/Qt on the Mac and Linux, but you have to code on Windows. My question: Other than Java tools (NetBeans comes to mind) and REALbasic, is there another GUI development tool for the Mac? Is one needed? I've been experimenting with Free Pascal, with .nib support, but it would be nice if Xcode/IB supported other languages a bit better. It seems the UI tools are the main barrier to developing Mac-like apps in other languages. Sometimes, a desktop app is the best solution for something. Does that mean Obj-C is the only serious option on the Mac? Yes, I know -- I will try to set time aside for Obj-C this summer. But, it would be nice to have options.
