Social sharing pop up

Hi there,

I would be like to be able to create a pop-up box like Marketo has created for when someone downloads a piece of content. I think it's a really great feature. Link to image below. Does anyone know how to do this? Is this possible to set up in-house with your IT team?

Cheers!
Courtney
