Dejo ejemplo de código:

using System;
using System.Runtime.InteropServices;
using System.Web.UI;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Serialization;

using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using Microsoft.SharePoint.WebPartPages;

namespace WebPartBasico
{
    [Guid("b0be23ab-d436-4819-8f63-acb18bc8f40c")]
    public class HolaMundo : System.Web.UI.WebControls.WebParts.WebPart
    {
        public HolaMundo()
        {
            this.ExportMode = WebPartExportMode.All;
        }

        protected override void Render(HtmlTextWriter writer)
        {
            writer.Write("<h1>Hola Mundo!</h1>");
        }
    }
}

Un ejemplo usando algunos metodos de la clase HtmlTextWriter para formatear la salida:

using System;
using System.Runtime.InteropServices;
using System.Web.UI;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Serialization;

using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using Microsoft.SharePoint.WebPartPages;

namespace EjemploTabla
{
    [Guid("1dbb53ed-53f4-4c4f-b0bc-d1b40e473d85")]
    public class EjemploTabla : System.Web.UI.WebControls.WebParts.WebPart
    {
        public EjemploTabla()
        {
            this.ExportMode = WebPartExportMode.All;
        }

        protected override void Render(HtmlTextWriter writer)
        {
            writer.AddAttribute(HtmlTextWriterAttribute.Border, "1");
            writer.AddAttribute(HtmlTextWriterAttribute.Width, "100%");
            writer.RenderBeginTag(HtmlTextWriterTag.Table);

            for (int i = 0; i < 5; i++)
            {
                writer.RenderBeginTag(HtmlTextWriterTag.Tr);
                for (int j = 0; j < 5; j++)
                {
                    writer.AddAttribute(HtmlTextWriterAttribute.Align, "center");
                    writer.RenderBeginTag(HtmlTextWriterTag.Td);
                    writer.Write(string.Format("{0}, {1}", i.ToString(), j.ToString()));
                    writer.RenderEndTag();
                }
                writer.RenderEndTag();
            }
            writer.RenderEndTag();
        }
    }
}

También se pueden usar los métodos de esta forma:

writer.RenderBeginTag("b");
writer.AddAttribute("Align", "center");

Para añadir controles al método render:

Crear los controles y luego llamar al método RenderControl de los mismos:

using System;
using System.Runtime.InteropServices;
using System.Web.UI;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Serialization;

using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using Microsoft.SharePoint.WebPartPages;

namespace WebPartBasico
{
    [Guid("b0be23ab-d436-4819-8f63-acb18bc8f40c")]
    public class HolaMundo : System.Web.UI.WebControls.WebParts.WebPart
    {
        public HolaMundo()
        {
            this.ExportMode = WebPartExportMode.All;
        }

        protected override void Render(HtmlTextWriter writer)
        {
          Label etiqueta1 = new Label();
          etiqueta1.text="Prueba";
          etiqueta1.RenderControl(output);
        }
    }
}
