wxPython has multiple "designers", like Boa and SPE...but as for a way
to "draw a report", I think you're stuck with something like VBA in an
Office application or the "holy grail" of report generators, Crystal
Reports. Personally speaking, I find Crystal to be more difficult to
use than coding it myself. To each their own, I suppose.
