Beginner Guide for developing GUI for Pocket PC

Question

Hi all,
I have been developing Advanced Swing GUI for seven years now.
The time has come to write some to Pocket PC, and it doesn't look good.
I've searched the net for a mere beginners-guide and found nothing
there is no single A-to-Z tutorial which will tell you what to download and how to write you first program.
I am offering 15 Duke dollars for the kind member that will be kind enough to write a short "idiot's guide for writing a little gui app for pocket pc" post, including exactly what to download, how to configure, and what to write.
Such post would help me and the rest greatly
Thank you very much

Guide to installing and using CrE-ME JVM on a Handheld device:
Step A: Where to download the CrE-ME JVM from?
1. NSIcom.com has a 30-day free trail version of CrE-ME JVM and can be downloaded from the following link by clicking on �Download Free Evaluation�:
http://www.nsicom.com/Default.aspx?tabid=159
The version I downloaded was CrE-ME 4.1
2. To download additional specific packages for applications that use SWING, RMI, etc. Click on �View all downloads� and download from the packages listed.
Step B: Installing the JVM.
1. Connect the device to a desktop.
2. Install the CrE-ME version downloaded as you install any other application on your desktop.
3. While installing, the installer program will ask if you want to install at the default location or to specify a path. (I guess installing to the default location will make life easier). Therefore, the JVM will be installed on the handheld device.
4. Copy the additional packages downloaded to "\Windows\CrEme\lib" directory on the handheld device. Double click on the package (.CAB) file and it will configure itself.
5. Test the sample applications given in �\Windows\CrEme\demos\� to check the proper installation of the JVM.
Step C: Executing your applications.
C.1 Method 1
1. Write and compile the program in any IDE but remember to compile the programs with jdk1.4 as CrE-ME 4.1 supports JDK 1.4 or earlier.
2. Create a jar file of your application.
3. Write a link file (.lnk), specifying the classpath and the CrEme exe file in the following format:
255#"\Windows\CrEme\bin\CrEme.exe" -Of -classpath <full JAR file path> <main class name>
Ex: 255#"\Windows\CrEme\bin\CrEme.exe" -Of -classpath �\My Documents\Menu.jar� Menu
-Of is used to redirect the console output to be redirected to jscpout.txt file located in the root directory of your device. Use -Ob if you are using a console based application.
255 specifies the number of characters in the file, but instead of counting the characters you can use 255 which is the maximum (in general, it is seen that a higher value works but not a number less than the number of characters)
Also note that the classpath is in single quotes
4. Copy the link file to the handheld device and then double click on the link file to run the application and if the application doesn�t show up, you know where to look for the errors. The jscpout.txt file created in the root folder of your device due to the �Of parameter used in the link file, will contain the console output and thus the errors.
C.2 Method 2
1. Write and compile the program in any IDE but remember to compile the programs with jdk1.4 as CrE-ME 4.1 supports JDK 1.4 or earlier.
2. Create an executable jar file of your application using the Manifest.mf file to specify the main class.
Ex: Main-Class: <main class name>
Also remember to hit the return (enter) key at the end of manifest file.
3. Copy the jar file to the handheld device and double click on it to execute.
4. In case the output doesn�t show up, it could mean that there were errors executing the application and to check for errors use Method 1.
