My org's inside sales team is requesting that a task is assigned to them to follow up with a customer 30 days after they Close Won an Opportunity.

Is this possible? If so.. how? My org is already developed/in use. 
(Would need step by step instructions..)

I'm an "accidental admin" so even through I've Googled this, a lot, I'm still not finding exactly what I need.
