* Create a message dialog. Automatically adds an OK button that closes the dialog. To detect the close,
* add an action on the QDialog_CloseEvent. To change the message, use the return value and set ->Text.
* To detect a button click, add a QDialog_ButtonEvent.
*
* If you specify no buttons, a close box in the corner will be created that will just close the dialog. If you
* specify just a string in $strButtons, or just one string in the button array, one button will be shown that will just close the message.
*
* If you specify more than one button, the first button will be the default button (the one pressed if the user presses the return key). In
* this case, you will need to detect the button by adding a QDialog_ButtonEvent. You will also be responsible for calling "Close()" on
* the dialog after detecting a button.
