DialogWrapper with different buttons

I am developing a plugin where I need to display a dialog (I use DialogWrapper), and after the user clicks OK it does something with the model from the form. I am using the DialogWrapper to display a GUI Form. I created my custom class that extends this DialogWrapper class and it simply sets the title and initializes. I wanted to use a same class for multiple GUI forms. 

But now I need to create a dialog something like a Wizard, clicking next until the last screen, and at the end to click finish and execute the action. Is this possible with DialogWrapper?
