Are there any good RAD tools for Linux?

Factual Questions
1

I am looking for a good RAD tool, (preferably C++ or C# but I’m interested in hearing about all of them) for Linux.

Borland had Kylix, but it was never considered to be that good and as I understand it, it has been abandoned.

I have found Mono but one site says that it is not ready for commercial development. Anyone familiar with it and can give feedback (good or bad)?

Is there anything else out there?

This might actually be better fodder for IMHO.
Some would argue that whether or not “good RAD tool” is an objective or subjective determination.
You may wish to consider having a mod move this to IMHO for better results.

At the risk of being typecast, I’ll post the link to RealBasic

I wouldn’t call Mono a RAD environment, because AFAIK there’s no GUI builder. Their System.Windows.Forms support is still weak, so you can’t even design forms in Visual Studio on Windows and port them over to Mono; you have to write your UI in Gtk# and do it essentially by hand (but check out Stetic).

I think your best bet would be Kylix, if you can still find a copy. From what I saw of it, it was nearly as good as Delphi/C++Builder. However, it helps if you know Pascal… the CLX library at the core of Kylix makes heavy use of certain Object Pascal language features, like set types and method pointers, that had to be grafted onto C++ in an ugly way.

I’ve used Builder C++ for years. I’m guessing that Kylix will be very familiar to me. But since they seem to be dropping support for it, I was hoping to find a different tool.
