Email Notification

Need small app that monitors a file and when it is accessed, shows a pop-up window with a warning of "New Email Message". It should also play a .wav file. Both the File Path and .wav file settings should be located in a text file that can be changed. The popup window should have a "OK" button to close it and continue the monitoring process. Basically, I am monitoring a file for changes when a new email comes in and triggers a popup window to let the user know. They can then click the OK button and it goes away. The program should then continue the monitoring process.
