I haven't done much Qt programming, and all of it in C++, but anyway:

my approach is to subclass QFrame (or, here, QDialog makes sense), and,
in the constructor, set up the UI and call connect(...). In C++, there's
a connect macro -- is there a connect function in QtCore, maybe?
"welcome.ui.welcomeNext.connect(welcome.ui.welcomeNext, ..." doesn't
look right.
