Here is a rough way to do it with a UserControl:

public partial class btnControl : UserControl
    {
        public Label label = new Label();
        public TextBox box = new TextBox();

        public btnControl()
        {
            this.label = new System.Windows.Forms.Label();
            this.box = new System.Windows.Forms.TextBox();
            this.SuspendLayout();
            // 
            // label
            // 
            this.label.AutoSize = true;
            this.label.ForeColor = System.Drawing.Color.White;
            this.label.Location = new System.Drawing.Point(4, 7);
            this.label.Name = "label";
            this.label.Size = new System.Drawing.Size(35, 13);
            this.label.TabIndex = 0;
            this.label.Text = "label";
            // 
            // box
            // 
            this.box.Location = new System.Drawing.Point(110, 3);
            this.box.Name = "box";
            this.box.Size = new System.Drawing.Size(31, 20);
            this.box.TabIndex = 1;
            this.box.Enabled = false;
            // 
            // btnControl
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.BackColor = System.Drawing.Color.Blue;
            this.Controls.Add(this.box);
            this.Controls.Add(this.label);
            this.Name = "btnControl";
            this.Size = new System.Drawing.Size(144, 26);
            this.ResumeLayout(false);
            this.PerformLayout();
        }
    }

Then put it in your form:

private void Form1_Load(object sender, EventArgs e)
        {
            btnControl Control = new btnControl();
            this.Controls.Add(Control);
            Control.label.Text = "Home";
            Control.box.Text = "42";
        }
