[SalesForce] possible to access custom labels dynamically

In apex you can reference a custom label with system.Label.labelName, but is there a more dynamic way to get a custom label for example system.Label.get(labelName)? I can't find anything like this in the documentation but was hoping it was possible.

I'm trying to have custom labels for fields to support multiple languages. The list of fields I'm showing is built in the controller and displayed inside an apex:repeat tag so I can't hardcode the labels. Is there a way to accomplish this?

Thanks!

EDIT This is now possible! You can instantiate a dynamic visualforce component in Apex to get this.

public String getLabel(String myLabel ){
    Component.Apex.OutputText output = new Component.Apex.OutputText();
    output.expressions.value = '{!$Label.'+ myLabel + '}';
    return String.valueOf(output.value);
}

ORIGINAL ANSWER

No, you can't reference labels dynamically in apex. You can vote for this idea here. However, you can reference them dynamically from visualforce so you can put them on the page like so:

public class MyController
{
    public String mylabel{get; set;}

    public MyController()
    {
         mylabel='labelname';   
    }
}

<apex:page Controller="MyController">
    <apex:outputText> {!$Label[mylabel]} </apex:outputText>
</apex:page>

[SalesForce] Combine Custom settings with Custom Labels

Sdry, I have wanted to do exactly this ever since Custom Settings came out. The problem, though, is that there is no Apex API for Custom Labels (click the link to vote for the idea for it!), so Custom Labels cannot be dynamically retrieved or requested within Apex. However, it CAN, as of Spring 12, be done in Visualforce, using Dynamic Components.

Here, I think is what you are looking for in Apex (that cannot yet be done):

Custom Settings + Custom Labels IN APEX (**not yet possible**)

// Get the stored Custom Setting record for User Preferences
User_Prefs__c p = User_Prefs__c.getInstance(UserInfo.getUserId());

// Get the stored ISO Code
String isoCode = p.ISO_Code__c;

// Get the running user's language
String languageKey = [
    select LanguageLocaleKey from User 
     where Id = :UserInfo.getUserId() 
     limit 1
].LanguageLocaleKey;

// Get the translation of the ISO Code corresponding to this user's language
// **THIS IS NOT POSSIBLE YET IN APEX**
String translatedCode = System.Label.getLabel('ISOCode_'+isoCode).getTranslation(languageKey);

And here would be an equivalent if you are using Visualforce:

Custom Settings + Custom Labels IN VISUALFORCE (possible right now)

/* APEX CONTROLLER */
public class Controller {

    public String getStoredISOCode() {
        // Get the stored Custom Setting record for User Preferences,
        // and return the ISO code
        return User_Prefs__c.getInstance(UserInfo.getUserId()).ISO_Code__c;
    }

}

/* VF PAGE */
<apex:page controller="MyController">

    <b>ISO Code</b>{!storedISOCode}
    <b>Translated</b>{!$Label['ISOCode_' & storedISOCode]}

</apex:page>
