I do not recommend using QtOctave, which is an abondoned and unmaintained 
project.
Octave now has its own GUI which, although experimental, is already MUCH better 
than QtOctave:

first you should install the package:
http://www.gnu.org/software/octave/doc/interpreter/Installing-and-Removing-Packages.html#Installing-and-Removing-Packages

unless you have a very peculiar geometry that really requires it I definetly 
recommend starting with secs1d rather than secs3d.
All secs*d packages have undergone lots of transformation recently, but new 
release has been held back due to this bug:
https://savannah.gnu.org/bugs/?func=detailitem&item_id=38236

an example of how to comput one bias point of a diode is given here:
http://octave.sourceforge.net/secs1d/function/secs1d_dd_gummel_map.html

just loop over the range of bias you are interested in to create an IV plot

QDDGOX is meant for nanoscale MOSFET simulation.
Is that what you are aiming at?

have you ever been using Octave before?
Do you need help with plotting in general or just about how to generate IV data?
