The easiest way to add a dropdown to the web part properties is to define it as an enumeration.  That will automatically be converted to a dropdown in the web part properties panel.  This site has an example of how to do an enum.

I'm not sure that will work in your case since your list will probably change over time.  To add a dropdown property that can be populated at run time you would need to create a custom tool pane for the webpart.  Here's an article on creating a custom editor panel.

you can create a custom editor part the custom editor part will inherit from editor part

public class CustomEditorPart : EditorPart

you need to override 3 methods 

CreateChildControls 

in the above method you will create your custom controls 

ApplyChanges

will save changes from your custom controls to webpart properties

SyncChanges

load the webpart properties to the custom controls 

in your webpart place the below code to utilize the custom editor part

 public override EditorPartCollection CreateEditorParts()
        {
            List<EditorPart> editors = new List<EditorPart>();
            editors.Add(new CustomEditorPart { ID = this.ID + "_editPart1", Title = "your custom title" });
            return new EditorPartCollection(editors);
        }
        public override object WebBrowsableObject
        {
            get
            {
                return this;
            }
        }
