functions from TwentyTen

Hello friends,

I created a theme based on all the functions from the default theme “TwentyTen” i.e. used its functions.php file

Reason is that I am not good with php or in creating WP functions myself.

QUESTION:
If i provide the theme for others to use then will it cause problem with reference to GPL ?
If YES then how to solve this issue?

Kindly guide me in this matter
