WPF XAML格式：如何正确放置这些控件（并使按钮在单击时正常运行）

因此，我是WPF的新手。实际上，这是我的第一个WPF项目。我来自UNIX桌面（和Web）编程背景，所以我对编程或标记语言并不陌生。

Q1：首先，我的应用程序是一个简单的对话框，无法最小/最大化或调整大小（为简单起见），因此我不介意固定（即硬编码）我的布局。

使用HTML进行解释，这就是我希望“表单”看起来像的样子：

<div>
    <div>
        <span>This is my Left Adjusted Title</span>
        <span>Some Right Adjusted Stuff</span>
    </div>
    <div>
        <div>
             <div>This is the parent container</div>
             <div>
                  <div>Title for option 1</div>
                  <div>
                       Radio Button for option 1
                  </div>

                  <div>Title for option 2</div>
                  <div>
                       Radio Buttons for option 2
                  </div>
              </div>
        </div>
        <div>
             <span>Right Floated Button</span>
        </div>
        <hr />
        <div>
            <div>These are the Results</div>
            <textarea>
                Vertically scrollable text here (nice if can be color formatted with underlines etc) ...
            </textarea>
        </div>
        <div id="footer">
            <div><a href='http://www.google.com'>Click here</a></div>
        </div>
    </div>
</div>

另一方面，这是我的XAML（我从Visual Designer中将其合并在一起）：

<Window x:Name="wndMain" x:Class="MyApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:ews="clr-namespace:ExtraWindowStyles"
        ResizeMode="NoResize"
        ews:ExtraWindowStyles.CanMinimize="false" 
        ews:ExtraWindowStyles.CanMaximize="false"         
        Title="Hello World" Height="501.492" Width="842.285">
    <Grid>
        <GroupBox Header="Input Parameters" HorizontalAlignment="Left" Height="173" Margin="10,25,0,0" VerticalAlignment="Top" Width="801" >
            <StackPanel Orientation="Horizontal" Margin="0,0,96,0">
                <StackPanel Margin="10">
                    <Label FontWeight="Bold">First Group</Label>
                    <RadioButton x:Name="opt11">Option 1 - 1</RadioButton>
                    <RadioButton x:Name="opt12">Option 1 - 2</RadioButton>
                    <RadioButton x:Name="opt13">Option 1 - 3</RadioButton>
                </StackPanel>
                <StackPanel Margin="10">
                    <Label FontWeight="Bold" Content="Second Group"/>
                    <RadioButton x:Name="opt21" Content="Option 2 - 1"/>
                    <RadioButton x:Name="opt22" Content="Option 2 - 2"/>
                    <RadioButton x:Name="opt23" Content="Option 2 - 3"/>
                </StackPanel>
            </StackPanel>

        </GroupBox>
        <Separator HorizontalAlignment="Left" Height="80" Margin="17,203,0,0" VerticalAlignment="Top" Width="794"/>
        <Button x:Name="btnSubmit" Content="Explore" HorizontalAlignment="Left" Height="34" Margin="632,203,0,0" VerticalAlignment="Top" Width="179" Click="btnSubmit_Click"  />
        <Label Content="Results:" HorizontalAlignment="Left" Height="28" Margin="10,242,0,0" VerticalAlignment="Top" Width="161"/>
        <Label Content="My App" HorizontalAlignment="Left" Height="23" Margin="696,439,0,0" VerticalAlignment="Top" Width="130" FontSize="9"/>
        <TextBlock>           
            <Hyperlink NavigateUri="http://www.google.com" RequestNavigate="Hyperlink_RequestNavigate">
                Click Here
            </Hyperlink>
        </TextBlock>
        <Rectangle Fill="#FFF4F4F5" HorizontalAlignment="Left" Height="162" Margin="17,270,0,0" Stroke="Black" VerticalAlignment="Top" Width="794"/>
        <Label x:Name="lblResult" Content="" HorizontalAlignment="Left" Height="157" Margin="17,275,0,0" VerticalAlignment="Top" Width="794"/>
    </Grid>
</Window>

如何修复此XAML，使其呈现为我在HTML代码段中显示的方式？

问题2：为什么WPF呈现的按钮的行为不像按钮？这真的很奇怪，单击时不会压下，如何获得“正常”按钮的单击行为？
