You could store a sketch and all the library files on an SD card. Then, all you'd need to do would be to program the one Arduino to compile and link that sketch. Are you up to writing a compiler and a linker that can fit in the Arduino's limited amount of memory?

You might be able to store a hex file, produced on the PC on an Arduino card, and then have one Uno read that and upload it to the other. Do some research.

okay thank you for the information.
