Based on the work of Bas Brekelmans above, I have also created two derivations -> "input" dialogs that allow you to receive from the user both a text value and a boolean (TextBox and CheckBox):

public static class PromptForTextAndBoolean
{
    public static string ShowDialog(string caption, string text, string boolStr)
    {
        Form prompt = new Form();
        prompt.Width = 280;
        prompt.Height = 160;
        prompt.Text = caption;
        Label textLabel = new Label() { Left = 16, Top = 20, Width = 240, Text = text };
        TextBox textBox = new TextBox() { Left = 16, Top = 40, Width = 240, TabIndex = 0, TabStop = true };
        CheckBox ckbx = new CheckBox() { Left = 16, Top = 60, Width = 240, Text = boolStr };
        Button confirmation = new Button() { Text = "Okay!", Left = 16, Width = 80, Top = 88, TabIndex = 1, TabStop = true };
        confirmation.Click += (sender, e) => { prompt.Close(); };
        prompt.Controls.Add(textLabel);
        prompt.Controls.Add(textBox);
        prompt.Controls.Add(ckbx);
        prompt.Controls.Add(confirmation);
        prompt.AcceptButton = confirmation;
        prompt.StartPosition = FormStartPosition.CenterScreen;
        prompt.ShowDialog();
        return string.Format("{0};{1}", textBox.Text, ckbx.Checked.ToString());
    }
}

...and text along with a selection of one of multiple options (TextBox and ComboBox):

public static class PromptForTextAndSelection
{
    public static string ShowDialog(string caption, string text, string selStr)
    {
        Form prompt = new Form();
        prompt.Width = 280;
        prompt.Height = 160;
        prompt.Text = caption;
        Label textLabel = new Label() { Left = 16, Top = 20, Width = 240, Text = text };
        TextBox textBox = new TextBox() { Left = 16, Top = 40, Width = 240, TabIndex = 0, TabStop = true };
        Label selLabel = new Label() { Left = 16, Top = 66, Width = 88, Text = selStr };
        ComboBox cmbx = new ComboBox() { Left = 112, Top = 64, Width = 144 };
        cmbx.Items.Add("Dark Grey");
        cmbx.Items.Add("Orange");
        cmbx.Items.Add("None");
        Button confirmation = new Button() { Text = "In Ordnung!", Left = 16, Width = 80, Top = 88, TabIndex = 1, TabStop = true };
        confirmation.Click += (sender, e) => { prompt.Close(); };
        prompt.Controls.Add(textLabel);
        prompt.Controls.Add(textBox);
        prompt.Controls.Add(selLabel);
        prompt.Controls.Add(cmbx);
        prompt.Controls.Add(confirmation);
        prompt.AcceptButton = confirmation;
        prompt.StartPosition = FormStartPosition.CenterScreen;
        prompt.ShowDialog();
        return string.Format("{0};{1}", textBox.Text, cmbx.SelectedItem.ToString());
    }
}

Both require the same usings:

using System;
using System.Windows.Forms;

Call them like so:

Call them like so:

PromptForTextAndBoolean.ShowDialog("Jazz", "What text should accompany the checkbox?", "Allow Scat Singing"); 

PromptForTextAndSelection.ShowDialog("Rock", "What should the name of the band be?", "Beret color to wear");
