This is supported on android 4.2 and up. You need to implement it via an App Widget. You can checkout the documentation here: http://developer.android.com/guide/topics/appwidgets/index.html#lockscreen
Depending on your requirements, you could possibly use Notifications, which appear on the lockscreen. http://developer.android.com/guide/topics/ui/notifiers/notifications.html
