Visual Python programming and decompilers?

Hi Guys

At work I have been exposed to a Agile Platform called OutSystems. It
allows you to visually program your web applications and I find the idea very intriguing.

So I have started to play around with the idea on how will I be able
to visually represent Python code as in the above image and then allow
the programmer to change some of the flow/code/logic visually and then
get it back as python source code. I don't know if this have been
tried before and after some googling I can't find anything like this,
so maybe I'm just lacking basic googling skills or a python solution
like the above does not exist yet.

If anybody knows of such solution please let me know, so that I don't
spend a lot of time recreating the wheel. Otherwise help me out on the
following problem:

I decided I can use byteplay3 to
disassemble the code to workable objects, It even allows me to rebuild
the objects to bytecode. So if I define patterns on how python
interrupts the source code to bytecode I can visually represent this
and also so convert my visual representations back to bytecode.

The only problem I have at the moment is how will I get this bytecode
back to python source code. I have googled for python decompiler but
only found old projects like unpyc, decompyle and some online
services. I would like to know if anybody know of a well maintained or
at least recent module that can help me accomplish the above
mentioned, because I'm hoping I can implement this in Python 3.1.

So any input or suggestion would be greatly appreciated.

Kind Regards,

Ludolph Neethling
