The ResolverOne spreadsheet was a normal spreadsheet program that wrote Python code under the hood. You could then add unit tests and validate your spreadsheet calculations. The company was sold but this web version https://github.com/pythonanywhere/dirigible-spreadsheet https://github.com/pythonanywhere/dirigible-spreadsheet remains and is open sourced. I also remember a project management tool that similarly wrote Python code under the hood. And then there is the Talend Data Integration toolkit which writes and compiles Java under the hood. There is a lot of this stuff kicking around these days if you care to hunt for it. However I think that workflow systems like Apache Taverna and jBPMN are more useful. You still write chunks of code but the framework glues it all together in a flexible manageable way instead of creating a Big Ball of Mud.
