[PyKDE] Is this possible in PyQt

I am wondering if this is possible in pyqt.  I would like to create a line
graph with the vertical axis 0 - 5 and the horizontal axis 0 - 500. I would
then like to input a text file with 10 values pairs in it.  the X values are
0,50,100,150,200 etc (every 50) the Y values gradualy increase from 1 - 5
forming a linear line.  What I would like to be able to do is create the
graph in pyqt and then "grab" the data points and move then in the Y axis
only and use bspline curves at those points to reshape the line.  Then I
would line to be able to create a new textfile with the refined data from
every iteration on the x axis ie. 0,1,2,3,4,5,6,7,8,9,10,11 etc. The file
would be 500 lines long.

I was wondering if this would be possible in pyqt.  I am using version 3.1
of Qt and the snapshot version of pyqt that compiles against 3.1.

The key thing is the ability the interactivly move the original points and
create a smooth curve and then generate the individual point data.

Any kind of help would be greatly appreciated
