The FindControl is failing because it can't find the control and causing a null reference.

Just reference it directly using FeedbackLabel as you already have it in your class. Just move the scope outside of your 'Init' method.

private Label feedbackLabel = new Label();
private TextBox inputTextBox = new TextBox();
private Button submitButton = new Button();

public void Page_Init(EventArgs e)
{
    feedbackLabel.ID = "FeedbackLabel";
}

protected void SubmitButton_Click(object sender, EventArgs e)
{
    feedbackLabel.Text =...;
}
