You could do this.
<Window x:Class="WpfApplication3.MainWindow"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="150" Width="525"
Background="LightGray">
<Window.Resources>
<Style TargetType="{x:Type Button}">
<Setter Property="Foreground" Value="White"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border BorderThickness="1" ClipToBounds="True">
<Border Background="Transparent" BorderBrush="Black"
BorderThickness="2" Margin="-2">
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center"/>
<Border.Effect>
<DropShadowEffect ShadowDepth="0" BlurRadius="10" Color="Blue"/>
</Border.Effect>
</Border>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid>
