Identify user controls on ADOBE, SAP, JAVA

We are developing a context sensitive HELP-system for users of - ADOBE eForms, - SAP GUI with scripting - SAP GUI without scripting - JAVA which enables the user to receive detailed information with one mouse click in any position. If the user needs help, he only has to click on an icon and the help system will know, which field is active and the individual help-information will be displayed, based on the specific field. Therefore we need to know a method, how to detect these non standard user controls, because the developer of these systems did not use the standard Windows user controls. The most problem will be JAVA! Please write the program in any language, you want to. Please choose one or more Systems, you are real expert of.
