Is there a widget for GTK or Qt that would allow me to draw stock charts like this?

How about GTKGraph? Or see if you can pull something out of Grism? The author writes:

I draw stock charts using a GtkDrawingArea and a Cairo context. The charts are not animated, but if you resize the chart window, the chart automatically resizes (actually, it performs a redraw).

There's KD Chart for Qt.

Try this: NightCharts.

But you should keep in mind, that it's a self-made thing without any support and seemingly its development has been stopped already. So probably there may be a plenty of bugs.

And one more thing. IMHO it draws the most pretty pie charts among other Qt chart libraries.
