Viable seed will produce trees. After that it gets dicey. Supposedly half will be male caprifigs, and half will be female. The female half could be Common or Smyrna types depending on the parents. If they are Smyrna, you'll need a wasp to pollinate them. If Common, they may or may not fruit, and the fruit may or may taste good. My initial, and limited, experience has been that about 10% gave you something useful. The last group of seedling, about 50 in number have yielded zero fruit and do not look promising. The 10 before that have very distinctive leave, but no fruit after several year. If you want to play, go for it. If you want fruit, buy a tree or root known cuttings.
If you are sincere in seeking knowledge and use what you learn, no question is stupid.
