You can use Google Data Java Client Library, include the JAR in your projects and use these:

import com.google.gdata.client.*;
import com.google.gdata.client.calendar.*;
import com.google.gdata.data.*;
import com.google.gdata.data.extensions.*;
import com.google.gdata.util.*;
import java.net.URL;

To create a new calendar event, you might use the following code:

URL postUrl =
  new URL("http://www.google.com/calendar/feeds/liz@gmail.com/private/full");
EventEntry myEntry = new EventEntry();

myEntry.setTitle(new PlainTextConstruct("Tennis with Darcy"));
myEntry.setContent(new PlainTextConstruct("Meet for a quick lesson."));

Person author = new Person("Elizabeth Bennet", null, "liz@gmail.com");
myEntry.getAuthors().add(author);

DateTime startTime = DateTime.parseDateTime("2006-04-17T15:00:00-08:00");
DateTime endTime = DateTime.parseDateTime("2006-04-17T17:00:00-08:00");
When eventTimes = new When();
eventTimes.setStartTime(startTime);
eventTimes.setEndTime(endTime);
myEntry.addTime(eventTimes);

// Send the request and receive the response:
EventEntry insertedEntry = myService.insert(postUrl, myEntry);
