Yes, you can charge for GPL software, but you must provide access to the source and anyone else can redistribute it at no charge under the same terms, among other restrictions. What you cannot do is take GPL code and redistribute it under an incompatible license (e.g., a license that restricts the rights to modification and distribution) in modified or original form. There is no obligation to distribute your modifications, but if you do, you must abide by the terms of the license.
