I am not a gtk expert and i am not a native English speaker, but i have a few English corrections for you:

> The problem make me headache is:

Better: "Here is the problem that gives me headache:"

> gtk2-perl can't be installed by cpan or ppm on M$ easily.

Better: "from CPAN" or "using the CPAN shell".

> I don't have any try on embedding before.

Better: "I didn't try embedding before" or "I don't have any experience with embedding before."

Hope it helps.
