If you want to connect your google calendar with korganizer you need kcaldav from AUR: kcaldav.

Now you can import your google calendar into korganizer:
- open korganizer (or kontact)
- click on the green '+' symbol to add a new calendar

- you can get the calendar name, when you open google calendar in your browser, then go to
My calendars click on the down arrow for the calendar you want to import and select Calendar settings
- copy the name of the calendar; the default name would be <name>@gmail.com
- enter your username and password in the appropriate fields
Now you should be able to use google calendar from within korganizer.
