A couple of comments:

I assume this prints to a consol rather than the GUI?

>   def __init__(self):
>   def main(self):


I assume putting main inside the class is a GTk thing? 
Its a bit unusual in normal OOP since every instance will 
have a main() which is not the usual intention of main() functions...

> if __name__ == '__main__':
> convert = Conversion_GUI()
> convert.main()

Why not simply

   Conversion_GUI().main()

Since you don't use convert anywhere.
