I need help with Triggers

[Freyleyes]

I have started a new map project and I need some help with triggers.If anyone of you guys out there could help me, please do so.

I can only use GUI Triggers and not JASS so please try to make it it GUI, if not JASS would do.

Help I need so far :

1) Make knock back spells.
2) Make jumping spells.
3) Nova Spells.
4) Creep revival that can create random groups of creeps like in dota.

Thanks in advance

Here's an amazing knockback script. The guy who submitted it is super pro.
