I think William is right about developing natively on the beaglebone. The GUI design could be done from other desktop and copied to BBB, or done natively. So are the cpp files (if you are using C++, I don't know how to do other languages like Python or bonescript). But all the program files (to me there are only four: mainwindow.h, mainwindow.cpp, mainwindow.ui, and mian.cpp) should be kept together into a single folder (the folder's name should be the project's name), and compiled and built by very simple command as follows: 1) qmake - project; 2) qmake; 3) make.
