Back around 2002 or so, I used to use PythonCard for in-house tools. PythonCard was a kind of a cross between HyperCard and Visual Basic and used wxWidgets for the UI elements. It was really excellent software.
The simplicity of it. No programming was needed to create the UI. It used a dialog editor like the one from Visual Basic. It was pretty fun to use.
You just had to drag-and-drop a control on the form. Handling events was just as easy. In the dialog editor you could association a standard event (like mouse or keyboard events) with a python function.
If you really wanted to, you could edit the event code because it was all just dictionaries, but you didn't need to.
