Finding a tool for code coverage in exploratory manual testing (without unit tests and command line)

1. These tool should write code coverage in a runtime mode (like Bullseye for C++ as my colleague tells me, but I don't know exactly and can't confirm it). I think it seems like Selenium IDE, but the result of testing shouldn't transform to junit for code coverage process, instead it should generate the visible report in a runtime mode or after testing.
2. The manual testing in this case is implied as exploratory testing or testing by strict following of check-lists.
3. We want such situation to do: we install some tool/plugin, make some manual tests in a runtime mode by testing some web-application, a tool/plugin simultaneously write code coverage and finally generate a report. There is no need to write some additional commands or code for coverage process launch.
4. Before writing this question here I've red a lot of materials about Sonar, Clover, Cobertura, Cassandra, Emma, JaCoCo, Visual Studio, dotCover, Хdebug all over the net, including StackOverFlow. Unfortunally all of them didn't fit my task - they work only with unit tests or through command line.
5. This task is not for solving problem of some our project. We prepare some educational materials for testers and we put there some info concerning tools of code coverage. These materials should be used both as for automated as for manual testers, but predominantly for the last ones.
6. Is such tool exist or not? :) Thank you in advance.
