One solution would be to use the confirm-method in Window, showing
the standard Javascript confirm popup which is modal and returns
the moment, the user confirms (or denies) the question:
if (Window.confirm(CONSTANTS.AreYouSure())){
letBadThingsHappen();
}

If you want to use a GWT Dialog-box you can solve that by
calling a callback-function:
MyPanel.java:
[...]
MyConfirmDialog mcd = new MyConfirmDialog(this);
mcd.center();
public void onUserConfirmed(boolean clickedYes){
if (clickedYes){
letVeryBadThingsHappen();
}
}
MyConfirmDialog.java
public MyConfirmDialog(MyPanel parent){
super(false, true);
this.parent = parent;
}
...
yesButton.addClickLister(...
public void onClick(final Widget sender){
hide();
parent.onUserConfirmed(true);
}
);
noButton.addClickListener(...
public void onClick(final Widget sender){
hide();
parent.onUserConfirmed(false);
}
}

Above should give you an idea.
