In XD, it is impossible to breed, because you can put only one Pokémon in the day care.
If you want to breed someone, you must trade it in GBA versions.
i was going to do that i really just want to trade across to my gba version but i jut want to know if i can get them to breed and give birth to a child with the elemental hyper beam
No they aren't egg moves so it isn't possible. The only way you can have a starter with an elemental hyper beam is to use the one that you got from Mt. Battle. The elemental beams are pretty useless anyway.
