Its really easy:

dlg=QtGui.QDialog()
dlgui=Ui_Dialog()
dlgui.setupUi(dlg)
if( dlg.exec_() == ... ):
...

The Ui_Dialog class you created in designer only contains code that adds
the widgets to a given QDialog or QWidget parent. Its not a QDialog
subclass anymore. The approach above of course only works if you don't
need extra code to handle the dialog. If you do you'd create a subclass
from QDialog and do the same thing as with the mainwindow (self.ui =...
self.ui.setupUi(this)). This is documented in the Qt4 designer manual,
to be found on doc.trolltech.com/4.2
