Since it is a super fast grower, starting from seed is actually easy. Your problems will be...
1. It is super fast grower...will take so much effort to keep it in check as a bonsai.
2. Leaves are big and "compounded"...for bonsai, smaller is preferred.
3. Soft wood...to me it matters, to some it doesn't.
4. This is a tropical tree (not sure where you are since you did not update your profile yet
)
As I said, if you really want to, you can definitely try it but for the effort, you will be better off working on other more bonsai suitable trees. The traits I look for...woody, small leaves, nice small flowers, nice small fruits, fall colors, backbuds well, root fast, nice bark, etc. Just a wishlist most of the time I only get several out of these and sometimes, I compromise.
Oh one big thing now...well adapted to local weather. Too much work for non-domestic plants.
