Is it possible to use a calendar as a desktop wallpaper (it could be a simple calendar application pinned to the desktop)?
I am hoping for something looking like this:
Ideally the calendar should sync to Google calendars.

Install dates 
Open Dates
In Calendar > Properties > create new
Provide the link to ical (.ics) calendar; remove https://
install compizconfig-settings-manager 
Open Startup Applications
Add

Open CompizConfig Settings Manager
Go to Window Management -> Window Rules

In Size rules (adjust to your monitor) 
Go to Window Management -> Place Windows -> Fixed Window Placement
Under Windows with fixed positions (you might want to set Y = 24(task-bar height), to show the menu bar)

Thank you Kory Wnuk for the inspiration your answer gave me.
using conky and gcalcli

One way is to use conky to do that task. Here's a tutorial for it.
Basically it says to use gcalcli to connect to your Google calendar, and use the .conkyrc script there to display it. you can change fonts and colors in that file too.
There's a more detailed Ubuntu forums thread about it.
You could use Rainlendar
The normal version is free; the version including network synced calendars costs ~10€. I got to say, though, those 10€ a couple years ago rank among my best value-for-money purchases ever.
