Are there any good, free RAD programs for Linux (to create web applications)?

What do you mean by web application? This could be many things. In what programming language???

Remember that there are few good RAD environments for windows ... and even less for linux.

If you want to write java code take a look at www.eclipse.org With this you can make stuff that works with java plugin.

I am actually looking to start learning any language. On Windoze I use Visual Studio.NET (programming in VB.NET). That lends itself to RAD well. Is there anything comparitive in Linux?

I can't help you more unless you say what do you understand by Web Application.

I started programming in VB myself, but back then (before VB.NET) it was so poor as a programming language (actually VB is a scripting language) that when I found Delphi I never went back, and if god is good I never will. I say back then because I heard that VB.NET is a hole different deal.

To build internet integrated stuff on linux I think you should consider learning Java. PHP is the equivalent of ASP under linux and is used to build dynamic web pages. Pascal is great to build programs for desktop, but on linux you don't have Delphi, so internet integrated stuff will be harders to build with pascal.

Stuff I recomend:

To program with object pascal: http://www.lazarus.freepascal.org/

This is the best tool I know to build gui programs under linux. Very powerful and also RAD. But, still far from Delphi's stability, small exes, easy to use or integrated internet stuff.

To program with Java: http://www.eclipse.org/

Good to build java applets or java programs. This can be integrated to web pages. You can also use javascript on html pages directly.

There is an interface that integrates php to eclipse.
