Default programmattically disable radio + wifi

I'd like to programmatically disable the radio (or at the very least disable texting and calling) and wifi connection on my samsung galaxy S3 (SGH-I747M)
I cant use any apps or widgets because it cant easily be undone by children.

I've searched the internet for a few days and really cant find the answers I'm looking for.

The phone is rooted, and I've disabled things such as camera sound and unlock with volume buttons before.

I'm not sure if this is in the right forum because it is technically a question... but it directly pertains to modifying??
