Hi I write the GUI code and make it as *.exe (stand alone application). But I want to delete main file (*.exe) in specific date/Time to prevent extra use. How can I do this?

This is a bad idea. Do not do this. People will be able to undo it anyways.
That being said, just call out to the system to delete the files.
delete('file.ext')

There are some cross-checks that can be done, such as examining the dates of other files to see if any of them are in the "future".
There are techniques such as contacting a remote site and asking it for the current time using an encrypted transmission. It is difficult to make this completely secure, though. (Quantum Encryption.)
If you are not able to use quantum secure channels, then there is no way to really prove what time it "really" is. At most you can make it a nuisance for people to break the software.
If your program is sufficiently valuable, then people will find a way to break it. There are people who specialize in doing this just to prove that they can, that they are more clever than you. Therefore the best way to ensure that your program does not get broken is to make your software so useless than no-one would want to use it.
