Perhaps I don't understand you rneed. However I guess you could use a postgis or, if you not quite smart with dbms , a spatialite. Define a table with three geometries (geom, point and line), and define a trigger. After this you can edit the polygon geometries with qgis. And when you commit the edit , the trigger will transfer transforming the geometry in the line and point.
Is this what you need ?
