Is there anyway to bridge between Azure Service Bus queue and a WebSphere queue?
Preferably "something" hosted in Azure, rather than an on-premise product
There is a wiki page How to Send message from an on premise IBM MQ to Azure Service Bus queue which introduce for the needs. You can follow it to create a program, either as a continous web job on Azure if using Azure App Service, or running on Azure VM if you want.
If the WebSphere MQ works on network within public IP, I think it's simple without any other additional work for network configuration. If not, you can try to create an Azure VPN Gateway to establish secure & cross-premises connectivity between them for message transfering.
You can use Azure Logic Apps, there are connectors for Azure Service Bus and WebSphere MQ.
