Convert Dot Net Application to run on Apple Mac

We have a small widget program developed in VB dotnet that presents a few screens of read only data. The data is retrieved from a web service.
There is very little user input other than mouse clicks.
The user does not interact with the data other than to print it.

We need the functionality of our widget to be converted to run on apple mac computers.

Sample screens attached
Image1 - widget1.png - show the widget open (clicked from windows taskbar)
