Help Required for Choosing Programming Language

No, but if that's your believe ..
Some examples:
- Creating a treeview (like in the M$ explorer), with full edit capabilities and full drag & drop
facilities: Delphi takes about 40 lines of code (most of them even ^C ^V).
- Creating a graphical overview of relations between database tables, which can be graphical
manipulated by the user (like in M$ Access): Delphi 20 lines of code.
I wonder what this costs in Python ?

I'm not an (educated) programmer, so I don't always use the right terms :-(
If I look at a well established program like DIA,
and see that it still can't repaint it's screen always correctly, ...
If I just look at MathPlotLib ;-)
But I also know one beautiful program based on wx: KICAD.

I've been using Python for just 2 months, and didn't try any graphical design,
I've other priorities first.
I would love to see:
- a comparison between wx and gtk (QT doesn't have a very inviting license ;-)
- some Python applications that uses one of these graphical libraries.

To give you an impression of some features I'm after, I've prepared an animation (not completely
ready yet), of the program I've written in Delphi, with both embedded MatLab and embedded Python,
where MatLab or Python does all the real-time numerical analysis.

Writing this program, including teaching myself Python (with a lot of help of this group, thank you
all !!), and writing the bloodpressure analysis in both MatLab and Python, excluding the 
ADC-drivers, costed me about 150 .. 200 hours ...
... can that be done be an experienced programmer in Python.

cheers,
