DESIGN ME A GUI FOR DATA COMING FROM MQTT

I need you to develop some software for me. I would like this software to be developed for Windows . I need a user interface for my IoT project. There are some devices sending and receiving messages over MQTT. I can take the messages from clients directly from ready to go client softwares(already written). But I want to publish messages by using buttons and slidebars. In the same time I want to convert the messages from subscribed topics to virtual Leds on my gui. So I have a IoT device sending data and receiving data over mqtt. But I dont want to write message to send a data to that devices. I want to send messages to that devices by pressing a button or sliding a slidebar on the GUI. I dont want to see messages directly from device. I want to see the messages with graphical interface like virtual leds. I have more than one devices and I want to see them on google maps api. When I click a pointer on google maps api, the gui of that device must be shown at that popup. And if I click on another pointer(device) on map it must open a new popup. Or it must refresh the device gui. You can use paho, it supports so much programming languages. But dont forget I need a reconfigurable GUI. I want to add new devices, I want to change buttons and leds in the future. But it is not big problem cause I can edit the codes easily after you explain me the blocks of code.
