Not _exactly_... they are (more or less) source-compatible on the major 
release numbers, and binary-compatible on minor releases (an app compiled 
for 3.0.x will not run with Qt 3.3.x libs).

Anyway, I'd also suggest to port the app to Qt 4 and/or to use the Qt 3 
support module of Qt 4 (not really a "port" then).

... which can get complicated meanwhile :).

Experience is what you get when you were expecting something else.
