Graphical tool

Good morning everybody, I'm writing here to ask you if somebody know about any graphical tool that can be used to generate the XML file for the OROCOS deployer.

I'm talking abut a tool that allows the user to add blocks (component) which have some properties (period, priority, scheduler, ...) and that can be connected using wires.

I'm thinking about something like matlab simulink or NI labview, which is very helpful and user friendly.

Does something like that already exist?

Thank you,

Best regards,
