Wait while downloading and installing
Checkmark: [X] Create icon on Desktop [X] Add icon to Start Menu
Click Finished
Start Gambas this way:
Start / All Programs / Cygwin-X / XWin-Server
From hidden taskbar right corner icons select icon that has black C and in middle of it light green X. From there click Programming / Gambas3.
Curious to know the experience on the Gambas apps produced in Windows. I guess they would also need Cygwin?
I also think that on Windows Cygwin is required.

"Will you port Gambas to Windows™ ?
I won't, but I will help any people trying to do that.
Gambas already runs under Cygwin. Note that there is a lot of things to port, if you want to do a native port: process management, gb.qt4 component, and so on... This is a huge job. The most promising compiler target would be Mingw-w64, which also allows cross compilation on a unix-like system."
If you use Gambas for making web apps, then you could use webbrowser to access those apps. Gambas IDE has wizard for web app, and some components that can be dragged to form. From some forum discussions I have read that debugging those web apps is easier then debugging php apps.
