Update: MonoDevelop version 2.2 and higher officially supports Windows. You can get the latest version here: http://monodevelop.com/Download
There is currently no official release of Monodevelop for Windows. After learning a bit, it seems that MonoDevelop was launched as the port of SharpDevelop, which is an open .Net IDE for Windows. You might want to check out SharpDevelop and see if it fits your needs.
You can find more information on the SharpDevelop website:
http://www.icsharpcode.net/OpenSource/SD/
You can target the Mono environment when writing applications in SharpDevelop (something you cannot do with Visual Studio Express). I should have indicated this in my answer above. On the website:
SharpDevelop has the ability to compile its code against a previous version of Microsoft.NET Framework, Microsoft Compact Framework or Mono (an open source .NET Framework-sponsored implementation of the .NET Framework), if installed.
