Apart from one minor release in the Qt4 cycle, Qt is binary compatible. You 
probably mean that different systems have different versions installed. Which 
is something the user/admin have to deal with. If you depend on a certain 
version of a lib, its a dependency...

You don't need the Qt sources to compile a qt-app. Most of your users already 
have the qt packages containing the libs. Otherwise they couldn't use qt 
apps. For compiling your app from source, they just need the -dev packages.

Qt is already included in ubuntu. No need to install it by hand or from 
source. Either you tell your users to fetch all the dependencies (lots 
of -dev packages) and install your app from source, or you create your own 
ubuntu packages. Which isn't so hard if you know how to compile applications 
(which you seem to know when you are developing).

Have fun,
