Probably the simplest approach would be this: you can just work around this problem is you embed a Web browser in your Form.
See, for example:

Sorry, the code sample is in VB.NET, but it should be enough to understand the idea.
Also, if I'm not much mistaken, Google map is used in the
System.Windows.Forms
application (this time, written in C#) in this CodeProject article, only it's only a part of this work dedicated to GSP:
Mapping with a GPS and C#[
