Hi, you can use a serial interface using MAX232 as this chip has an on board bootloader. the software tool you need is: https://www.flashmagictool.com/

you can make your circuit and at anytime connect to it using a serial connection and program it. remember that the crystal should be connected and the chip should be in operating mode to program. To do it all automatically you can add two transistors in your circuit. in this way you can program it in your circuit without the press of a button. Please look at the attached circuit:
