Can we display degrees, minutes, seconds in QGIS Print Composer window instead of decimal degrees?
Is there any plugins available for that?
For reference, this setting is found under the map item properties panel, "show grid" -> "draw coordinates" -> "format":
You will be able to do that in a future version, as it has just been implemented:

I doubt there is any c++ plugin out there already extending it.
