Make a system service and install a systemwide keyboard hook. Means you have to create two projects. A system service that keeps running and a DLL that is used for the hook...

However, you will really annoy quite a lot of people with such an application and it is considered a very bad practice in general. Besides, you cannot prevent all keys from being pressed. (Some special keys will always be detected.) Furthermore, a simple copy&paste could make it possible for users to still use certain characters, even if you block the keys.
