Sorry if this doesn't answer your question, but as a fellow starting modder, I find the easiest way to make something new is to study how the existing stuff works. I played very briefly with this, making a custom fireball spell with a knock back by adding the Unrelenting Force magic effect to a duplicated spell. You can only learn an adept destruction spell from a tome or a merchant when.
Just be aware how things are categorized, and how the combination of magic effects might turn out. Sets targets on fire, dealing 33 of the immediate spell damage over 2s Intense Flames Fear, 99 pts for 15 secs if the Intense Flames perk has been unlocked Fire (HazardWallofFireSpell), 20 damage every 1 second and tapers for another. Do new spells (Adept/Expert/Master) become available on the merchants after. At the very least, I would recommend tracking down existing spell that already function similar to what you want, and examine how they accomplish it.

Actually, I believe modifying an existing spell would be the best approach, especially for somebody just starting into modding. Read on to learn the basics of Furnishing Crafting, a new system available.
