I know there are several problems in doing that (the login credentials need to be sent, the page code is full of javascript that will hardly work in Servoy etc), but Servoy surprised me so many times that I think it’s worth of a try
I haven’t looked at it, but it sounds like it should be doable. Below is Google’s info on it:

How can I view my calendar from other applications?
A “Private Address” lets you easily view a read-only version of your calendar from other applications. Using this address, you can access your calendar from various applications, such as a feed reader (like Google Reader) or a product that supports the iCal format (like iCal for Mac.)
To obtain your calendar’s “Private Address,” follow these steps:
Under “Calendars” in the left column, click on the down-arrow next to the appropriate calendar, then select “Calendar settings.” (Alternatively, click on “Manage Calendars” under “Calendars” in the left column, then click on the name of the appropriate calendar.)
In the “Private Address” section, click on the “XML” or “iCal” icon. A pop-up window with your calendar’s private URL will appear.
Additionally, you can export your calendar information by clicking on the “ICAL” button and clicking on the displayed URL.
Note: The private address was designed for your use only, so be sure not to share this address with others. If you want to let other people see your calendar, share your calendar’s public address (“Calendar Address”) with them. If you accidentally share your calendar’s private address, click the “Reset Private URLs” link to regenerate your calendar’s private address.
