Aha, I see.  Depending on how you created the buttons this may be OK,
and it may not.  Do you get a different return value from your Run
method depending on which button you clicked?

Also, I would not have the dialog destroy itself.  The caller should
be responsible for that, since it created it.  What you may want to do
instead is have a static method:

public static int Run(string title, string message, out result) {
    PromtingDialog pd = new PromtingDialog(title, message);
    try {
        int retval = pd.Run();
        result = pd.response;
        return retval;
    } finally {

Usually the pattern you would use if you were going to create and use
this dialog from other code without using a static method would be to
make the "result" field accessible by a public property and let the
dependent code check it directly:

PromtingDialog pd = new PromtingDialog(title, message);
try {
    if (pd.Run() == (int) ResponseType.Accept) {
        // do something with pd.Response
} finally {

(BTW, it should be PromptingDialog.)
