Change GUI library from DevExpress to standard .net forms

I have a utility written in C# in VS2008. Unfortunately the GUI uses a library named DevExpress (you can google it) and I want it to be changed to the standard GUI library of .NET so that no external libraries will be required. The most problematic part to transfer would be to change the menu items? of the commands as they contain controls inside them (in the menu). In order to do this in standard form controls, clicking on a command should open a new dialog with the paramaters. Also I'd like to add a simple functionality -? every 30 minutes a popup should appear, saying "This application is not registered". If you think you can do this, send me a message and I'll give you the zip file of the project for you to evaluate and send a bid.
