No its that the problem ...

Of course that I tried, but I am new in OOP and just can't find the way that it must be done... I don't wanna do it for me, I just ask to guide me which Panel to use, and how to achieve this effect, I achieved only by the simplest way

        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="*" />
                <RowDefinition Height="5*" />
                <RowDefinition Height="*" />
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="4*" />
            </Grid.ColumnDefinitions>
            <Image Source="img/img1.png" Grid.Row="0" Grid.Column="0" />
            <Label Grid.Row="1" Grid.Column="0" Content="E-Mail:"/>
            <Label Grid.Row="2" Grid.Column="0" Content="Comment:"/>

            <TextBox Grid.Column="1" Grid.Row="1" Margin="3" />
            <TextBox Grid.Column="1" Grid.Row="2" Margin="3" />
            <Button Grid.Column="1" Grid.Row="3" HorizontalAlignment="Right" 
                MinWidth="80" Margin="3" Content="Send"  />
        </Grid>

Again I just ask to show me the way, not to do it instead of me...
