Answer 1

I assume your page's content is a Canvas control:

Code behind:

protected void ButtonGenerate_Click(object sender, RoutedEventArgs e)
{
    TextBox tb = new TextBox();
    (this.Content as Canvas).Children.Add(tb);
}

You may find other textbox property in https://msdn.microsoft.com/en-us/library/system.windows.controls.textbox(v=vs.110).aspx

Answer 2

Just give your grid a name in xaml :

<Grid x:Name="Grid1">
    <Button Grid.Column="0"
            Margin="10"
            Click="btnGenerate_Click">
        Button Content
    </Button>
</Grid>

and in code behind :

private void btnGenerate_Click(object sender, RoutedEventArgs e)
{
    //Get the number of input text boxes to generate
    int inputNumber = Int32.Parse(textBoxInput.Text);

    //Initialize list of input text boxes
    inputTextBoxes = new List<TextBox>();

    //Generate labels and text boxes
    for (int i = 1; i <= inputNumber; i++)
    {
        //Create a new label and text box
        Label labelInput = new Label();
        Grid1.Children.Add(labelInput);
        TextBox textBoxNewInput = new TextBox();
        Grid1.Children.Add(textBoxNewInput);
    }
}

If you want, you can set the position also so that the newly created elements doesn't overlap each other.

EDIT :

You need to create a grid with required rows and columns and then place each textbox or label inside the required row-column combination. It contains 6 rows and 3 columns. Please see the example below :

<Grid Name="Grid1">
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition />
        <RowDefinition />
        <RowDefinition />
        <RowDefinition />
        <RowDefinition />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition />
        <ColumnDefinition />
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
</Grid> 

private void btnGenerate_Click(object sender, RoutedEventArgs e)
{
    //Get the number of input text boxes to generate
    int inputNumber = Int32.Parse(textBoxInput.Text);

    //Initialize list of input text boxes
    inputTextBoxes = new List<TextBox>();

    //Generate labels and text boxes
    for (int i = 1; i <= inputNumber; i++)
    {
        //Create a new label and text box
        Label labelInput = new Label();

        Grid.SetColumn(labelInput, i);
        Grid.SetRow(labelInput, i);
        Grid1.Children.Add(labelInput);

        TextBox textBoxNewInput = new TextBox();
        Grid.SetColumn(labelInput, i+1);
        Grid.SetRow(labelInput, i);
        Grid1.Children.Add(textBoxNewInput);
    }
}
