I'm sorry I should have mentioned that my interest is in C or C++
I want something that will generate C++ code that can then be compiled for native(not interprited code) execution and make really fast executables.
Nothing out there that doesn't take work if you are looking to use C/C++.
Basically to compile C++ code on all those operating systems you need to be able to run all of those on a machine or several machines. Here is what I used to do.
I used Visual Studio from Microsoft. I ran VMWare and had an instance of every operating system running that I wanted to compile code for. I then wrote an plugin for Visual Studio to send my code, along with any building commands and options needed, to the proper VM system running through the loop back network adapters I created to talk between WMware instances. I would use something like Putty to send things back and forth. I created a few buttons with the plugin for each of the build types I was trying to accomplish.
So basically I could hit one button at the end at the top of my toolbar to batch compile my code for every operating system I had running as a VMware.
It took a long time to write and it wasn't simple to do so. Especially since Visual Studio 2008 with the new IDE for plugins had just came out. Which means the documentation was sporadic at best at the time.
I just use CMake + git for my x-platform C++.
He wanted a visual editor though.
