Grid is more powerful then StackPanel and suited for more granular and complex designs/layouts

Exmaple

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
        <RowDefinition Height="28" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition Width="200" />
    </Grid.ColumnDefinitions>
    <Label Grid.Row="0" Grid.Column="0" Content="Name:"/>
    <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="0" Margin="3" />
    <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>

You can use usercontrol.

<UserControl x:Class="StackoverflowTest.UserControl1"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         xmlns:local="clr-namespace:StackoverflowTest"
         mc:Ignorable="d" 
         d:DesignHeight="100" d:DesignWidth="300"
         Name="TestBtn">
<Button>
<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="1*"/>
        <ColumnDefinition Width="2*"/>
    </Grid.ColumnDefinitions>
    <Image Grid.Column="0" Source="{Binding Path=Source,ElementName=TestBtn}"  />
        <TextBlock Grid.Column="1" Text="{Binding Path=CustomText,ElementName=TestBtn}" Background="Aqua" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
</Button>

Code in usercontrol.cs(Add dependencyproperty)

    public UserControl1()
    {
        InitializeComponent();
    }

    public ImageSource Source
    {
        get { return (ImageSource)GetValue(SourceProperty); }
        set { SetValue(SourceProperty, value); }
    }

    public string CustomText
    {
        get { return (string)GetValue(textProperty); }
        set { SetValue(textProperty, value); }
    }

    public static readonly DependencyProperty SourceProperty =
    DependencyProperty.Register("Source", typeof(ImageSource), typeof(UserControl1));


    public static readonly DependencyProperty textProperty =
    DependencyProperty.Register("CustomText", typeof(string), typeof(UserControl1));
}

And you can easy to use this usercontrol.

<Grid>
    <local:UserControl1 x:Name="PlayBtn" Width="100" Height="30" Source="play.png" CustomText="Play" />
</Grid>
