Custom Editor to create GO and fill in text fields from CSV file

UPDATE: Afterthought, Maybe I'll do it at run time instead, that way I can manage memory as the GO's can be destroyed once used.

Hi,
Does anyone have a custom editor script example to do the following:

I have a quiz system that works by having a parent GO(Question Manager) and multiple child objects under the parent GO(Question Manager). Each child GO(Question Creator) has a script with number of string variables: Question type, Question, AnswerA,AnswerB .. ,CorrectAnswer.

The Question Manager iterates through the child objects and reads the current childs variable (for each) and populates button text on a relative UI element.
All this works fine! it automatically sets up the UI type and populates data for current question

====================
Requirement: Avoid the labour of manually adding Question GO's and Populate from an external list instead.

My next ambitous step is to be able to import a CSV of Q&A's that can read line by line and generate a child GO called QuestionCreator. It then needs to add the Question Creator Script and populate string variables that are read from the current line in the CSV field.

I have no knowledge of custom editors and would really appreciate a working exmaple to get me started!

Any help much appreciated!

Cheers
