 public static void CreateSubsites(SPWeb web)

           Hashtable templatewebInformation = new Hashtable();
           templatewebInformation .Add("URL", "siteurl");
           templatewebInformation .Add("TemplateName", "template name");
           templatewebInformation .Add("Title", "site title");
           templatewebInformation .Add("Description", "site Description");
           templatewebInformation .Add("LCID", "1033");
           SPWeb temlateNewWeb = CreateSite(web, templatewebInformation );

          Hashtable templatewebInformation1 = new Hashtable();
           templatewebInformation1 .Add("URL", "siteurl1");
           templatewebInformation1 .Add("TemplateName", "template name1");
           templatewebInformation1 .Add("Title", "site title1");
           templatewebInformation1 .Add("Description", "site Description1");
           templatewebInformation1 .Add("LCID", "1033");
           SPWeb temlateNewWeb = CreateSite(web, templatewebInformation1 );
         }

Creating the Site
------------------
public static SPWeb CreateSite(SPWeb web, Hashtable webInformation)
       {
           SPWeb newWeb = null;
           if (webInformation["TemplateName"] == null)
               return newWeb;
           SPDocumentLibrary solutions = (SPDocumentLibrary)web.Site.GetCatalog(SPListTemplateType.SolutionCatalog);
           // Get Web Template
           SPWebTemplateCollection webTemplates = web.Site.RootWeb.GetAvailableWebTemplates(1033);
           SPWebTemplate webTemplate = null;
           foreach (SPWebTemplate item in webTemplates)
           {
               if (item.Name.Contains(webInformation["TemplateName"].ToString()))
               {
                   webTemplate = item;
               }
           }
           if (webTemplate != null)
           {
               if (webInformation["URL"] == null)
                   return newWeb;
               string URL = webInformation["URL"].ToString().Trim();
               if (string.IsNullOrEmpty(URL))
                   return newWeb;
               string title = webInformation["Title"] == null ? URL : webInformation["Title"].ToString();
               string description = (webInformation["Description"] == null) ? string.Empty : webInformation["Description"].ToString();
               uint LCID = (webInformation["LCID"] == null) ? 1033 : Convert.ToUInt32(webInformation["LCID"]);
               bool useUniquePermissions = false;
               bool bConvertIfThere = false;

               using (SPWeb subWeb = web.Webs.Add(URL, title, description, LCID, webTemplate, useUniquePermissions, bConvertIfThere))
               {
                   subWeb.AllowAllWebTemplates();
                   subWeb.Navigation.UseShared = true;
                   newWeb = subWeb;
               }
           }
           return newWeb;
       }
