Answer 1

Ok, given that I may have not been the kindest to you on the other thread (and I'm still annoyed that you went and cross-posted this), and that you did actually use code tags, I'm going to post some code here:
Please take the following advice onboard though.
1. When you are naming your artifacts, please use the java coding standard as your guide. So if you are naming a class you use a capital letter first, and use camel case thereafter. All method names begin with a lower case letter, and all variable names begin with a lower case letter (and again camel case after that)
2. Please use self explanitory names (for everything), so no more row1, row2, or text1, text2, etc.
3. The example I am giving below makes use of a single class to handle all actions, this is not really the best way to do this, and a better way would be to have a class to handle each action (that would remove the massive if() else if() in the action handler class.
4. When you are using class variables they should be private (no exceptions, ever!), if you need to access them from other classes use accessors (eclipse and other IDE tools can generate these methods for you in seconds)
5. Notice the naming convention for my constants (final statics), they are all upper case (again from the java coding standards document, which you are going to look for with google right?)
6. I have hived some of the creation work to helper methods (the getSubjectTextField() etc), although it isn't advisable to be calling other methods from the constructor, since this is a GUI, and you want it to appear as soon as you create the class, we won't worry about this, but perhaps as an execrise you could work out a better way to do this?
7. Personally, I don't like classes that implement listeners, unless they are specifically designed to do that job. So a Frame that is set up as an action listener is fine, provided the actions it listens for are associated with the frame, not its contents. If the actions are related to its contents, then a dedicated class is better.
8. Another personal opinion, but I feel it makes code clearer, but others may disagree. If you are creating a variable solely to hold the result of a calculation, to be passed to a method in the very next line, then don't create the variable, just pass the method as the argument to the method (feel free to ignore this advice if the method call is extremely long, and a local would make it easier to read)
Anyway, here is the code. I have removed most of the menu items, and leave this as an exercise for you. Also I have only created 2 methods (new and exit), I'll again leave it as an exercise for you to complete this.
