Create Windows utility to monitor connected clients

[Hadz369]

Start with a simple utility that can receive connection notifications from NATS and display the number of connected clients.

The utility must be written in a language that is cross platform.

The UI should contain:

• A text block for dynamically updating the connected clients with 0 as the default value. The text block will be read only.
• A label to the left of the text block titled "Connected Clients"
• A button titled "Clear" which clears the contents of the text block.

The utility should subscribe to NATS to listen for connection status notifications.

• A connection status message will contain the client host name and a subscription id.
• The subscription id must be an integer value unique to the client.
• The hostname must be an alphanumeric string value with no spaces or special characters.
