Visual GUI Maker creates both a .c code file as well as a compiled tool file.
The buttons of the created GUI can be configured to send either ARexx or DOS commands.
If you are familiar with "Command Panel Creator" (CPC), another one of my "bloated" programs, then you can think of this as the next generation of that application.
The current Version is V1.0.
