For drawing paths, you could try to refer to Shapes and Basic Drawing in WPF Overview.

The bubble tooltip is in the Grid, you can set the length and width of the Grid to set its size.

<Grid Width="300" Height="100">  
            <Path Fill="LightSkyBlue" Stretch="Fill" Stroke="#FF000000"   
                  Data="M 0,40 L5,45  L5,75 C5,75 5,80 10,80 L160,80 C160,80 165,80 165,75 L165,10 C165,10 165,5 160,5 L10,5 C10,5 5,5 5,10 L5,35 Z" />  
        </Grid>
