These are two very separate questions - I'd create a separate thread for
the area of a contour one.

For the question of writing text on an image - I'd do this with VTK. So
setup the normal VTK/Qt connection (QVTKWidget):
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Qt/RenderWindowUIMultipleInheritance

then write your text using:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/DisplayText
or
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/VectorText
