And we're about to release Español Llano, the Spanish version of Plain English. This new compiler compiles Spanish and English. Or both, even in the same sentence. Kind of like a bi-lingual human.
Our Plain English development system - unique interface, simple file manager, elegant text editor, hexadecimal dumper, native-code-generating compiler/linker, and wysiwyg page layout facility (for documentation) - 25,000 sentences, is hardly a trivial application. Yet we wrote it, conveniently and efficiently, entirely in Plain English. And the "ambiguity" of the language actually helped.
In Plain English you can, for example, say "Clear the screen" or "Erase the screen" or other similar phrases and still get the same result. So we could type our thoughts the way we happened to be thinking them at the moment, and didn't have to remember (or look up) the exact syntax of the routines we wanted to call.

And the whole shebang (less than a megabyte!) is here:

Just download and unzip. No installation necessary. Exactly the same on any version of Windows from XP to 10.
Please address questions and comments directly to me:
Yes, our compiler is Windows only and generates native machine code for Intel x86 architecture. It looks and feels the same on any Windows version from XP to 10.
The false positives that some virus programs return are typically due to the fact that our executable is different that what they expect. Specifically, it doesn't have all the unnecessary crap that typical compilers churn out -- only what's essential, and nothing more. Some programs also object to files with no extension (like .txt or .src). We left these off since they're not very English-like.
