    What kind of Widget should I use to draw on, and how do I do it?

In the HP widget set, you can use the WorkSpace widget.

    The thing that bothers me is that this error does not occur
    at the time of the XDrawRectangle call, but later.

That's because of the asynchronous nature of X.  If you can
run your application with -synchronize, it would have happened
at the time of the call.
