Here's an example I made real quick to get you started. 

<Style TargetType="Button"

                x:Key="styleA">

            <Setter Property="Template">

               <Setter.Value>

                  <ControlTemplate TargetType="Button">

                     <Grid x:Name="RootElement"

                           Background="Transparent">

                        <Grid.Resources>

                           <Storyboard x:Key="MouseOver State">

                             

                              <DoubleAnimation Storyboard.TargetName="buttonScale"

                                               Storyboard.TargetProperty="ScaleX"

                                               To="1.2"

                                               Duration="00:00:00.25"/>

                              <DoubleAnimation Storyboard.TargetName="buttonScale"

                                               Storyboard.TargetProperty="ScaleY"

                                               To="1.2"

                                               Duration="00:00:00.25" />

                           </Storyboard>

                           <Storyboard x:Key="Normal State">

                              <DoubleAnimation Storyboard.TargetName="buttonScale"

                                               Storyboard.TargetProperty="ScaleX"

                                               To="1"

                                               Duration="00:00:00.25" />

                              <DoubleAnimation Storyboard.TargetName="buttonScale"

                                               Storyboard.TargetProperty="ScaleY"

                                               To="1"

                                               Duration="00:00:00.25" />

                           </Storyboard>

                          

                           <Storyboard x:Key="Pressed State">

                              <DoubleAnimation Storyboard.TargetName="buttonScale"

                                               Storyboard.TargetProperty="ScaleX"

                                               To="1.4"

                                               Duration="00:00:00.25" />

                              <DoubleAnimation Storyboard.TargetName="buttonScale"

                                               Storyboard.TargetProperty="ScaleY"

                                               To="1.4"

                                               Duration="00:00:00.25" />

                           </Storyboard>

                        </Grid.Resources>

                        <ContentPresenter Content="{TemplateBinding Content}"

                                          RenderTransformOrigin="0.5,0.5">

                           <ContentPresenter.RenderTransform>

                              <ScaleTransform x:Name="buttonScale" />

                           </ContentPresenter.RenderTransform>

                        </ContentPresenter>

                     </Grid>

                  </ControlTemplate>                 

               </Setter.Value>

              

            </Setter>

         </Style>

 You'll want to affect the content of the button to what you need, for example :

 <Button Width="100"

              x:Name="buttonTest"

              Style="{StaticResource styleA}"

              Click="buttonTest_Click">

         <StackPanel Orientation="Vertical">

            <Image Source="image1.jpg" />

            <TextBlock Text="Test 1" />

         </StackPanel>

      </Button>

Modify the storyboard states to reflect what you need for your RenderTransform etc...
