Showing all newform.aspx of a certain content type in a dynamic list

Question

How can I provide the following solution?

• on the 'home page' of a site collection, query all lists with a certain content type ('eForms')
• each list entry will be a link to the 'newform.aspx' of that particular list

I find that currently we are manually maintaining a list to all of our eForms which is becoming quite cumbersome. We do have the ability to apply content types to these lists so a CQWP or otherwise can 'latch onto' them and pull it. The problem is, I don't want the individual items within the list to appear on the CQWP, but rather need to just link to the "newform.aspx" so users can easily navigate to submit new form data.

Is this possible?

Here's a solution in C# (assuming that you'll use the code in a visual webpart):

protected void Page_Load(object sender, EventArgs e)
    {
        var eForms = new List<EForm>();
        foreach (SPWeb web in SPContext.Current.Site.AllWebs)
        {
            var listsWithWantedContentType = web.Lists.Cast<SPList>()
                .Where(list => list.ContentTypes.Cast<SPContentType>()
                .Any(ct => ct.Name == "Item"));
            foreach (var list in listsWithWantedContentType)
            {
                eForms.Add(new EForm
                               {
                                   ListUrl = list.RootFolder.ServerRelativeUrl,
                                   ListTitle = list.Title,
                                   NewFormUrl = list.DefaultNewFormUrl
                               });                    
            }

            web.Dispose();
        }
        gvLists.DataSource = eForms;
        gvLists.DataBind();
    }

    class EForm
    {
        public string ListUrl { get; set; }
        public string ListTitle { get; set; }
        public string NewFormUrl { get; set; }
    }

gvList is a GridView control that you'll put inside the webpart ascx control.

<asp:GridView ID="gvLists" runat="server" AutoGenerateColumns="True"></asp:GridView>
