Do other Python GUI toolkits require this?

I'm stopping after this because it is offtopic noise, but take a
graph of position vs time for an object; the slope of that graph
happens to be related to the velocity of the object, so you can
'see' the velocity of the object even though the graph is of
position and time. The slope of the graph can be said to describe a
rate. 

(and a graph that showed the movement of the world around that
object would be quite different, and similar lines on those
different graphs would thus elecit rather different descriptions,
which is the point, pretending that all graphs of learning curves
only describe what you assume they describe and then being pedantic
about what information can be inferred from the graphs isn't going
to get you anywhere, hence this thread) 

My english is full of colloquialisms and idioms and I am not
interested in learning "Antoon Pardon's Dictionary of Exact Usage",
so I fear that further explanation will be fruitless.
