You need to create Custom Web Part Editor with DropDownList

Creating a Custom Web Part Editor in SharePoint 2010

and using SharePoint Object Model to fill this dropdownlist like this (not tested):

SPListCollection docLibraryColl = SPContext.Current.Web.GetListsOfType(SPBaseType.DocumentLibrary);
foreach (SPList list in docLibraryColl) 
{
    SomeDropDownList.Items.Add(list.Title, list.Id);
}
