Creating app for mini2440

This is my first time dealing with the mini2440. I am currently using qt
designer to create an app for the mini2440. However I can't seem to install
it or run it on the mini. What are the steps that I need to take to copy
the necessary files over and to install/run it? Thanks for the help in
advance.

Maybe you could use Qt Script. The advantage of scripts is, that they
doesn't need to be compiled with a cross compiler or so (thats good if you
change many things - you don't need to recompile again and again). But a
working, cross compiled Qt with interpreter must be installed on mini2440.
