Where do i get parts for diy hardware wallet and program

By DIY I guess you mean not a pre-built product like a Trezor.
Any electonics store or distributor (Mouser, Farnell, etc etc etc) will sell you parts to make any of the open-source options listed in https://en.bitcoin.it/wiki/Hardware_wallet
To pick a random easy example: pi-wallet - though a compute-module or zero-W would be more compact. There's plenty of open-source hand-held, battery-powered gaming devices based on that hardware that could be adapted to suit.
If you are more ambitious, and handy with a soldering iron, you could check out something like BitBox which is apparently based on standard electronics parts. They publish schematics and bill-of-materials for parts as well as the code. You'll not match their production quality but a functional portable device should be achievable with the right skills.
