New to Java. Want to write a simple applet for a mobile phone.

Question

Hello,
I want to write a simple java applet for a mobile phone. currently I am in the stage of thinking about whether this is possible in a timeframe of about a month. I have very little java experience from a while back so I'm pretty much starting from scratch.
All I want is an applet that lets you send 2 or 3 variables to an online server. The server will then reposition telescopes.
All i'm concerned with is the mobile phone part, which doesn't have to be secure or impressive. Just a simple interface.
Ideally it should work on my nokia 6070, which occording to the official specs has the following java technology:
MIDP 2.0
CLDC 1.1
JSR 120 Wireless Messaging API
JSR 135 Mobile Media API
Nokia UI API
(I don't know what any of this means but am a good learner).
Can anyone offer me any advice? Is this possible in my timeframe? where should I start? I need a editor and compiler also (I'm using windows XP).
Many thanks and kind regards,
Jason

Actually it is working on my phone now.
I changed the target platform in the wireless toolkit settings to MIDP 1.0
Now to create the fields coordinate fields etc. I don't have much of a clue really.
Current I have:
import java.io.*;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class AtmosMIDlet extends MIDlet implements CommandListener
Form WelcomeForm = new Form("AtmosMIDlet");
StringItem WelcomeMes = new StringItem(null, "Please enter coordinates:");
TextField Longitude = new TextField("Longitude", "", 3, TextField.NUMERIC);
TextField Lattitude = new TextField("Lattitude", "", 3, TextField.NUMERIC);
public AtmosMIDlet()
try
ImageItem logo = new ImageItem(Image.createImage("/logo.png"));
WelcomeForm.append(logo);
catch (java.io.IOException x)
throw new RuntimeException ("Image not found");
WelcomeForm.append(WelcomeMes);
WelcomeForm.append(Longitude);
WelcomeForm.append(Lattitude);
WelcomeForm.addCommand(new Command("Exit", Command.EXIT, 0));
WelcomeForm.setCommandListener(this);
public void startApp()
Display.getDisplay(this).setCurrent(WelcomeForm);
public void pauseApp() {}
public void destroyApp(boolean unconditional) {}
public void commandAction(Command c, Displayable s)
notifyDestroyed();
I'm trying to get the image logo.png to display at the top but I get the error:
C:\WTK25\apps\AtmosSpec\src\AtmosMIDlet.java:19: cannot find symbol
symbol : constructor ImageItem(javax.microedition.lcdui.Image)
location: class javax.microedition.lcdui.ImageItem
ImageItem logo = new ImageItem(Image.createImage("/logo.png"));
^

Build failed
When I try to build.. Any help would be great.
Ideally the image would be on a seperate screen for a couple of seconds.
