yes, actually what I wrote it is completely independent from QGIS, it
is compatible with pyqt/pyside and with python2/python3,
It is just a proof of concept. Now Francesco it is working to better
integrate this draft with QGIS stuff.

The idea was heavily based on formlayout code:

https://code.google.com/p/formlayout/

Basically each parameter is a GUI field that it is add to the main
window, therefore based on the parameter type the field could be:

if "raster"/"vector" => a combo box with the rasters/vectors available
if "integer" => a spinbox
if "string"/"double" => a text field
if "file" => a file dialog

based on the guisection parameter all the options are organized in tabs.

The code is under 500 lines of code.

I guess should be possible to follow the same approach using the wxpython.
I think that with a bit more effort should be possible to make it
general enough to make it independent from the GUI framework (Qt/Wx)
that we want to use.

I have not link to share at this stage because we are still working on it.
But I guess we can share the code as soon as we have something that it
is able to cover the basic needs.
