Stubbing and services tools use for "Integration testing"

Hi,
There're several tools to visualize services (stubs, drivers) and often use for integration testing. Some of them are purely focus on developers, some of them have GUI and more friendly.
In my experience, I use Mockey (https://github.com/clafonta/Mockey) , it's written by Java and have GUI for easy to simulate, trigger the request to see what my application during test cycles.
Is there any other tools that can be easily used by QC that had no exposure to programming nor command line tools? Preferably tools with GUIs? Please share.
