Here is the solution to make Google Recaptcha Addon Work in the free version of DW Question & Answer plugin

Into the file wp-content/plugins/dwqa-captcha/dwqa-captcha.php add the following code under the line 71 :

public function gl_public_key_display() {
	global $dwqa_general_settings;
	$public_key = isset( $dwqa_general_settings['captcha-google-public-key'] ) ?  $dwqa_general_settings['captcha-google-public-key'] : '';
	echo '<p><input type="text" name="dwqa_options[captcha-google-public-key]" value="'.$public_key.'" class="regular-text"></p>';
}

public function gl_private_key_display() {
	global $dwqa_general_settings;
	$private_key = isset( $dwqa_general_settings['captcha-google-private-key'] ) ?  $dwqa_general_settings['captcha-google-private-key'] : '';
	echo '<p><input type="text" name="dwqa_options[captcha-google-private-key]" value="'.$private_key.'" class="regular-text"></p>';
}

Then add the following code under the line 58 :

add_settings_field(
	'dwqa_options[captcha-google-public-key]',
	__( 'Captcha Google public key', 'dwqa' ),
	array( $this, 'gl_public_key_display' ),
	'dwqa-settings',
	'dwqa-captcha-settings'
);		

add_settings_field(
	'dwqa_options[captcha-google-private-key]',
	__( 'Captcha Google private key', 'dwqa' ),
	array( $this, 'gl_private_key_display' ),
	'dwqa-settings',
	'dwqa-captcha-settings'
);

Now you will be able to insert the Google API Keys into the plugin’s admin panel
