I believe Sofortblid would work with your camera and provide the features you need if you are on mac. (Other answer is windows only.) http://www.sofortbildapp.com
Assuming you are on Windows you could try out DigiCamControl (I'm not affiliated). They list the Nikon D3200 as partially supported. Live view works, however, you can't use manual focus in live view and can't set the focus area.
